Diaphragm electromyogram measured with unilateral magnetic stimulation. (1/2444)

The purpose of this study was to establish the phrenic nerve conduction time (PNCT) for magnetic stimulation and further assess the relatively new technique of anterior unilateral magnetic stimulation (UMS) of the phrenic nerves in evaluating the diaphragm electromyogram (EMG). An oesophageal electrode was used to record the diaphragm compound muscle action potential (CMAP) elicited by supramaximal percutaneous electrical phrenic nerve stimulation (ES) and UMS from eight normal subjects. The oesophageal electrode used for recording the CMAP was positioned at the level of the hiatus and 3 cm below. The diaphragm CMAP was also recorded from chest wall surface electrodes in five subjects. All of the phrenic nerves could be maximally stimulated with UMS. A clear plateau of the amplitude of the CMAP was achieved for the right and left phrenic nerves. The mean amplitudes of the CMAP recorded from the oesophageal electrode were, for the right side, 0.74+/-0.29 mV (mean+SD) for ES and 0.76+/-0.30 mV for UMS with maximal power output, and for the left side 0.88+/-0.33 mV for ES and 0.80+/-0.24 mV for UMS. PNCT measured by the oesophageal electrode with ES and UMS with maximal output were, for the right side, 7.0+/-0.8 ms and 6.9+/-0.8 ms, respectively, and for the left side 7.8+/-1.2 ms and 7.7+/-1.3 ms, respectively. However, the CMAP recorded from chest wall surface electrodes with UMS was unsuitable for the measurement of PNCT. The results suggest that unilateral magnetic stimulation of the phrenic nerves combined with an oesophageal electrode can be used to assess diaphragmatic electrical activity and measure the phrenic nerve conduction time.  (+info)

A clinical study of motor evoked potentials using a triple stimulation technique. (2/2444)

Amplitudes of motor evoked potentials (MEPs) are usually much smaller than those of motor responses to maximal peripheral nerve stimulation, and show marked variation between normal subjects and from one stimulus to another. Consequently, amplitude measurements have low sensitivity to detect central motor conduction failures due to the broad range of normal values. Since these characteristics are mostly due to varying desynchronization of the descending action potentials, causing different degrees of phase cancellation, we applied the recently developed triple stimulation technique (TST) to study corticospinal conduction to 489 abductor digiti minimi muscles of 271 unselected patients referred for possible corticospinal dysfunction. The TST allows resynchronization of the MEP, and thereby a quantification of the proportion of motor units activated by the transcranial stimulus. TST results were compared with those of conventional MEPs. In 212 of 489 sides, abnormal TST responses suggested conduction failure of various degrees. By contrast, conventional MEPs detected conduction failures in only 77 of 489 sides. The TST was therefore 2.75 times more sensitive than conventional MEPs in disclosing corticospinal conduction failures. When the results of the TST and conventional MEPs were combined, 225 sides were abnormal: 145 sides showed central conduction failure, 13 sides central conduction slowing and 67 sides both conduction failure and slowing. It is concluded that the TST is a valuable addition to the study of MEPs, since it improves detection and gives quantitative information on central conduction failure, an abnormality which appears to be much more frequent than conduction slowing. This new technique will be useful in following the natural course and the benefit of treatments in disorders affecting central motor conduction.  (+info)

The role of ventral medial wall motor areas in bimanual co-ordination. A combined lesion and activation study. (3/2444)

Two patients with midline tumours and disturbances of bimanual co-ordination as the presenting symptoms were examined. Both reported difficulties whenever the two hands had to act together simultaneously, whereas they had no problems with unimanual dexterity or the use of both hands sequentially. In the first patient the lesion was confined to the cingulate gyrus; in the second it also invaded the corpus callosum and the supplementary motor area. Kinematic analysis of bimanual in-phase and anti-phase movements revealed an impairment of both the temporal adjustment between the hands and the independence of movements between the two hands. A functional imaging study in six volunteers, who performed the same bimanual in-phase and anti-phase tasks, showed strong activations of midline areas including the cingulate and ventral supplementary motor area. The prominent activation of the ventral medial wall motor areas in the volunteers in conjunction with the bimanual co-ordination disorder in the two patients with lesions compromising their function is evidence for their pivotal role in bimanual co-ordination.  (+info)

The role of area 17 in visual imagery: convergent evidence from PET and rTMS. (4/2444)

Visual imagery is used in a wide range of mental activities, ranging from memory to reasoning, and also plays a role in perception proper. The contribution of early visual cortex, specifically Area 17, to visual mental imagery was examined by the use of two convergent techniques. In one, subjects closed their eyes during positron emission tomography (PET) while they visualized and compared properties (for example, relative length) of sets of stripes. The results showed that when people perform this task, Area 17 is activated. In the other, repetitive transcranial magnetic stimulation (rTMS) was applied to medial occipital cortex before presentation of the same task. Performance was impaired after rTMS compared with a sham control condition; similar results were obtained when the subjects performed the task by actually looking at the stimuli. In sum, the PET results showed that when patterns of stripes are visualized, Area 17 is activated, and the rTMS results showed that such activation underlies information processing.  (+info)

Magnetic measurements of pulmonary contamination. (5/2444)

The magnitic determination of pulmonary contamination is based on the remanent magnetization of ferromagnetic contaminating particles. The remanent field of the externally magnetized particles is proportional to their amount and shows their distribution. Although only magnetizable particles are detected with this method, the amount of the inhaled ferromagnetic substance can be used when the total dust exposure of the worker is estimated. In this work five shipyard welders were studied. First the particles disposed to the lungs were externally magnetized and then their distribution was mapped with a sensitive magnetometer. The magnitudes of the remanent fields measured from the welders differed from the fields measured from controls by several orders of magnitude. The radiographic findings showed a good correlation with the magnetic measurements, and further experiments will prove whether this method can partly replace presently used radiological investigations.  (+info)

The effects of static magnetic fields and X-rays on instability of microsatellite repetitive sequences. (6/2444)

To determine the genetic effect of static magnetic fields (SMF), which are not supposed to produce any significant DNA damage, we took advantage of DNA mismatch repair (MMR) deficient cells, in which all the errors produced during DNA replication are left uncorrected. We first established a simple and less labor-intensive method to analyze genetic changes in microsatellite repetitive sequences in the MMR-deficient cells. After exposure to a strong SMF (6.34T) for 24 h, both MMR deficient HCT116 cells and proficient HeLa S3 cells did not exhibit any significant effect on microsatellite changes. Moreover, when HCT116 cells were synchronized at the G1/S boundary by aphidicolin and exposed to SMF during the whole S-phase, no increase in microsatellite changes was either observed. In contrast, irradiation by a low dose X-ray (2Gy) significantly increased microsatellite changes in HCT116 cells. This suggested that exposure to strong SMF may not induce any significant level of genetic changes in microsatellite sequences.  (+info)

Magnetometric evaluation for the effect of chrysotile on alveolar macrophages. (7/2444)

Alveolar macrophages are thought to play an important role in fibrogenesis due to asbestos exposure. In this experiment, we evaluated the effect mainly by unique magnetometry and also by conventional methods such as lactate dehydrogenase (LDH) activity measurement and morphological observations. Alveolar macrophages obtained from Syrian golden hamsters by bronchoalveolar lavages were exposed 18 hours in vitro to Fe3O4 as an indicator for magnetometry and chrysotile for experiments. A rapid decrease of the remanent magnetic field, so called "relaxation", was observed after the cessation of an external magnetic field in macrophages phagocytizing Fe3O4 alone, while relaxation was delayed in those concurrently exposed to chrysotile. Since relaxation is thought due to the cytoskeleton-driven random rotation of phagosomes containing iron oxide particles, chrysotile is considered to interfere with the cytoskeletal function of macrophages. Release of LDH from chrysotile-exposed macrophages into the medium was recognized, but it was not significantly higher than the controls. Apoptosis was negligible in macrophages exposed to chrysotile by the DNA ladder detection, the terminal deoxynucleotidyltransferase-mediated dUTP-biotin nick end labeling method and morphological observations. Electron microscopical examinations revealed early necrotic changes in macrophages exposed to chrysotile. These findings indicate that cell magnetometry detects impaired cytoskeletal function due to in vitro exposure to chrysotile.  (+info)

Cortical control of spinal pathways mediating group II excitation to human thigh motoneurones. (8/2444)

1. The possibility was investigated that cortical excitation to human thigh motoneurones is relayed via lumbar premotoneurones. 2. Test responses were evoked by transcranial magnetic stimulation (TMS) in voluntarily contracting quadriceps (Q) and semitendinosus (ST) muscles: either a motor evoked potential (MEP) in surface recordings or a peak of cortical excitation in the post-stimulus time histogram (PSTH) of single motor units was used. These test responses were conditioned by stimuli to the common peroneal (CP) or gastrocnemius medialis (GM) nerves. 3. CP stimulation evoked a large biphasic facilitation of the Q MEP, with early, short-lasting, low-threshold (0.6-0.8 x motor threshold (MT)) and late, longer lasting and higher threshold (1.2-1.5 x MT) peaks separated by a period of depression. GM nerve stimulation evoked a similar early depression and late facilitation in the ST MEP. 4. CP-induced effects in the Q H reflex were different (smaller late facilitation not preceded by any depression), suggesting that CP and cortical volleys interact at a premotoneuronal level to modify the Q MEP. 5. Peaks of cortical excitation evoked by TMS in single motor unit PSTHs were modulated by the conditioning volley like the MEPs with, in Q motor units, early and late CP-induced facilitations separated by a depression, and in ST motor units a late GM-induced facilitation. Facilitations on combined stimulation (i) were greater than the sum of effects by separate stimuli and (ii) never affected the initial part of the cortical peak. 6. It is concluded that the features of the reported facilitatory interactions between cortical and peripheral volleys are consistent with interactions in a population of lumbar excitatory premotoneurones co-activated by group I and group II afferents. The potency of the effects suggests that a significant part of the cortical excitation to motoneurones of thigh muscles is relayed via these interneurones. 7. It is argued that the early depression in ST motoneurones and the separation of the two peaks of facilitation in Q motoneurones reflect a cortical facilitation of spinal inhibitory interneurones projecting on excitatory premotoneurones.  (+info)

TY - JOUR. T1 - Design of superconducting quantum interference device for magnetic immunoassays. AU - Enpuku, Keiji. AU - Ohba, Akihiro. AU - Inoue, Katsuhiro. AU - Soejima, Kazuyuki. PY - 2004/9/1. Y1 - 2004/9/1. N2 - A superconducting quantum interference device (SQUID) for application to biological immunoassays has been designed. In this application, the magnetic field from a magnetic marker made of magnetic nanoparticles is detected with the SQUID. It is shown that the conventional design of the SQUID that was developed for the case of uniform magnetic field cannot be used in this application, since the spatial variation of the magnetic field from the marker is large. Therefore, a numerical simulation method is developed for obtaining a signal flux detected with the SQUID when the magnetic field changes spatially. It is shown that the signal flux strongly depends on the geometrical parameters of the measurement system, such as the size of the pickup coil, size of the sample and the distance ...

A magnetic sensor array includes a first three-dimensional magnetic sensor secured to a substrate in a central location of the substrate. A number of second three-dimensional magnetic sensors are secured to the substrate at a first distance from the first magnetic sensor. Additionally, a number of one-dimensional magnetic sensors are secured to the substrate at a second distance from the first magnetic sensor greater than the first distance. Additional magnetic sensors of any dimension may also be included. The magnetic field sensitivity of the first and second three-dimensional magnetic sensors may be less than the magnetic field sensitivity of the one-dimensional magnetic sensors. The sensing range of the first and second three-dimensional magnetic sensors may be greater than the sensing range of the one-dimensional magnetic sensors. The magnetic sensor array may also include a processing circuit coupled to the magnetic sensors.
Exploring giant magnetic anisotropy in small magnetic nanostructures is of technological merit for information storage. Large magnetic anisotropy energy (MAE) over 50 meV in magnetic nanostructure is desired for practical applications. Here we show the possibility to boost the magnetic anisotropy of the smallest magnetic nanostructure-transition metal dimer. Through systematic first-principles calculations, we proposed an effective way to enhance the MAE of an iridium dimer from 77 meV to 223-294 meV by simply attaching a halogen atom at one end of the Ir-Ir bond. The underlying mechanism for the enormous MAE is attributed to the rearrangement of the molecular orbitals which alters the spin-orbit coupling Hamiltonian and hence the magnetic anisotropy. Our strategy can be generalized to design other magnetic molecules or clusters to obtain giant magnetic anisotropy. Strong magnetic anisotropic effects in nanostructures are an important property for materials to be used in spintronics and magnetic data
A DC SQUID has a first washer coil for forming a superconducting ring, Josephson junctions and a dampening resistor coupled to both ends of the first washer coil, and a shunting resistor connected in parallel to the Josephson junctions. An input coil is magnetically coupled with the first washer coil, and a first modulation coil is also magnetically coupled with the first washer coil. A ground plane comprising a superconducting film is disposed to cover an area of the Josephson junctions without covering the first washer coil for shielding the Josephson junctions from a magnetic noise. The ground plane prevents a magnetic flux trap from occurring, thus enabling stable operation of the DC SQUID. A washer cover comprising a superconducting film is disposed to cover only a slit portion of the first washer coil to prevent leakage of a magnetic field from the slit portion. The ground plane and the washer cover are simultaneously formed in a same layer of the DC SQUID. A second washer coil can be connected in
Nanostructured magnetic materials are important for various applications, and hence their development is critical for the advancement of science and technology. Coupling self-assembly to the generation of magnetic materials in a simple, straight-forward manner has remained a challenge. Here, a series of novel cobalt-functionalized block copolymers (BCPs) with various block ratios were synthesized using ring-opening metathesis polymerization (ROMP). These BCPs self-assembled into different nanostructured morphologies, including cylindrical, lamellar, and inverted cylindrical phases. Upon a simple heat treatment, all these nanostructured materials exhibited room temperature ferromagnetic (RTF) behavior due to the nanoconfinement of the cobalt species within one phase. The effect of dimensionality, or the degree of nanoconfinement, on the macroscopic magnetic properties was studied using superconducting quantum interference device (SQUID) magnetometer. The most highly constrained cylindrical morphology
Magnetic particle imaging (MPI) is a promising medical imaging technique producing quantitative images of the distribution of tracer materials (superparamagnetic nanoparticles) without interference from the anatomical background of the imaging objects (either phantoms or lab animals). Theoretically, the MPI platform can image with relatively high temporal and spatial resolution and sensitivity. In practice, the quality of the MPI images hinges on both the applied magnetic field and the properties of the tracer nanoparticles. Langevin theory can model the performance of superparamagnetic nanoparticles and predict the crucial influence of nanoparticle core size on the MPI signal. In addition, the core size distribution, anisotropy of the magnetic core and surface modification of the superparamagnetic nanoparticles also determine the spatial resolution and sensitivity of the MPI images. As a result, through rational design of superparamagnetic nanoparticles, the performance of MPI could be effectively

The discovery of magnetic skyrmions in ultrathin heterostructures has led to great interest in possible applications in memory and logic devices. The non-trivial topology of magnetic skyrmions gives rise to a gyrotropic motion, where, under an applied energy gradient a skyrmion gains a component of motion perpendicular to the applied force. So far, device proposals have largely neglected this motion or treated it as a barrier to correct operation. Here, we show that skyrmions can be efficiently moved perpendicular to an energy step created by local changes in the perpendicular magnetic anisotropy. We propose an experimentally-realizable skyrmion racetrack device which uses voltage-controlled magnetic anisotropy to induce a step in magnetic anisotropy and drive a skyrmion unidirectionally using alternating voltage pulses. ...
We developed a magnetic measurement method to measure the moisture content and hydration condition of mortar as a magnetic mixture material. Mortar is a mixture of Portland cement, sand, and water, and these materials exhibit different magnetic properties. The magnetization-magnetic field curves of these components and of mortars with different moisture contents were measured, using a specially developed high-temperature-superconductor superconducting quantum interference device. Using the differences in magnetic characteristics, the moisture content of mortar was measured at the ferromagnetic saturation region over 250 mT. A correlation between magnetic susceptibility and moisture content was successfully established. After Portland cement and water are mixed, hydration begins. At the early stage of the hydration/gel, magnetization strength increased over time. To investigate the magnetization change, we measured the distribution between bound and free water in the mortar in the early stage by ...
We report the synthesis of a room temperature ferromagnetic Mn-Ge system obtained by simple deposition of manganese on Ge(001), heated at relatively high temperature (starting with 250 °C). The samples were characterized by low energy electron diffraction (LEED), scanning tunneling microscopy (STM), high resolution transmission electron microscopy (HRTEM), X-ray photoelectron spectroscopy (XPS), superconducting quantum interference device (SQUID), and magneto-optical Kerr effect (MOKE). Samples deposited at relatively elevated temperature (350 °C) exhibited the formation of ~5-8 nm diameter Mn5Ge3 and Mn11Ge8 agglomerates by HRTEM, while XPS identified at least two Mn-containing phases: the agglomerates, together with a Ge-rich MnGe~2.5 phase, or manganese diluted into the Ge(001) crystal. LEED revealed the persistence of long range order after a relatively high amount of Mn (100 nm) deposited on the single crystal substrate. STM probed the existence of dimer rows on the surface, slightly elongated as
Nuclear magnetic resonance (NMR) signals are detected in microtesla fields. Prepolarization in millitesla fields is followed by detection with an untuned dc superconducting quantum interference device (SQUID) magnetometer. Because the sensitivity of the SQUID is frequency independent, both signal-to-noise ratio (SNR) and spectral resolution are enhanced by detecting the NMR signal in extremely low magnetic fields, where the NMR lines become very narrow even for grossly inhomogeneous measurement fields. Additional signal to noise benefits are obtained by use of a low noise polarization coil, comprising litz wire or superconducting materials. MRI in ultralow magnetic field is based on the NMR at ultralow fields. Gradient magnetic fields are applied, and images are constructed from the detected NMR signals.
Progressive miniaturization is an important driving force for technological progress. Nowadays, magnetic multilayer systems for magnetic sensors are comprised of individual films, which are often only a few atomic layers thick. Scientists from the Leibniz Institute of Solid State and Materials Research (IFW) Dresden and from the Forschungszentrum Dresden-Rossendorf (FZD) picked up the well-known fact that it is not sufficient to reduce the thickness of the individual layers to miniaturize these systems. Instead of using multilayer systems a promising alternative is to combine the magnetic properties of the different layer materials within a single film. This goal has now been achieved by scientists from Dresden who produced an ultra-thin striped layer. Traditional multilayer systems are made up of single layers consisting of hard magnetic and soft magnetic materials. Hard magnetic materials exhibit a stable magnetic configuration whereas the magnetization direction of soft magnetic materials can ...
The extreme sensitivity of SQUIDs makes them ideal for studies in biology. Magnetoencephalography (MEG), for example, uses measurements from an array of SQUIDs to make inferences about neural activity inside brains. Because SQUIDs can operate at acquisition rates much higher than the highest temporal frequency of interest in the signals emitted by the brain (kHz), MEG achieves good temporal resolution. Another area where SQUIDs are used is magnetogastrography, which is concerned with recording the weak magnetic fields of the stomach. A novel application of SQUIDs is the magnetic marker monitoring method, which is used to trace the path of orally applied drugs. In the clinical environment SQUIDs are used in cardiology for magnetic field imaging (MFI), which detects the magnetic field of the heart for diagnosis and risk stratification. Probably the most common commercial use of SQUIDs is in magnetic property measurement systems (MPMS). These are turn-key systems, made by several manufacturers, ...
A high-Tc dc SQUID (superconducting quantum interference device) gradiometer was developed for magnetic immunoassays where magnetic nanoparticles are used as markers to detect biological reactions. The gradiometer was fabricated on a 5 × 10 mm2 SrTiO3 bicrystal substrate and has a gradiometer resolution of 2.1 pT cm−1 Hz−1/2. A magnetic signal was detected from a sample of 1 μl of Fe3O4 nanoparticles in a 40 mg ml−1 solution kept in a microcavity fabricated on Si wafers with Si3N4 membranes using MEMS (micro-electro-mechanical-systems) technology. It was found that volumes as small as 0.3 nl in principle would be detectable with our present device. This corresponds to a total number of particles of 2.2 × 107. The estimated average dipole moment per particle is 4.8 × 10−22 Am2. We are aiming at reading out immunoassays by detecting the Brownian relaxation of magnetic nanoparticles, and we also intend to integrate MEMS technology into our system.
Quantum interference (QI) effects in molecular devices have drawn increasing attention over the past years due to their unique features observed in the conductance spectrum. For the further development of single molecular devices exploiting QI effects, it is of great theoretical and practical interest to develop simple methods controlling the emergence and the positions of QI effects like anti-resonances or Fano line shapes in conductance spectra. In this work, starting from a well-known generic molecular junction with a side group (T-shaped molecule), we propose a simple graphical method to visualize the conditions for the appearance of quantum interference, Fano resonances or anti-resonances, in the conductance spectrum. By introducing a simple graphical representation (parabolic diagram), we can easily visualize the relation between the electronic parameters and the positions of normal resonant peaks and anti-resonant peaks induced by quantum interference in the conductance spectrum. This ...
Abstract. Strontium titanate is a low-temperature, non-Bardeen-Cooper-Schrieffer superconductor that superconducts to carrier concentrations lower than in any other system and exhibits avoided ferroelectricity at low temperatures. Neither the mechanism of superconductivity in strontium titanate nor the importance of the structure and dielectric properties for the superconductivity are well understood. We studied the effects of twin structure on superconductivity in a 5.5-nm-thick layer of niobium-doped SrTiO3 embedded in undoped SrTiO3. We used a scanning superconducting quantum interference device susceptometer to image the local diamagnetic response of the sample as a function of temperature. We observed regions that exhibited a superconducting transition temperature Tc≳10% higher than the temperature at which the sample was fully superconducting. The pattern of these regions varied spatially in a manner characteristic of structural twin domains. Some regions are too wide to originate on ...

This study examined the applications of novel non-polymer magnetic ferrite nanoparticles (Fe3O4 NPs) labeled with 99mTc-pertechnetate (99mTcO4 −). The radiochemistry, chemistry, and biodistribution of Fe3O4 NPs labeled with 9mTcO4 − were analyzed. This paper employed instant thin layer chromatography and magnetic adsorption to evaluate the labeling efficiency and stability of 99mTc-Fe3O4 at various reaction conditions. A scanning electron microscope, X-ray diffractometer, Fourier transform infrared spectrometer, laser particle size analyzer, and superconducting quantum interference device magnetometer were used to analyze the physical and chemical properties of the Fe3O4 and 99Tc-Fe3O4 nanoparticles. The biodistribution and excretion of 99mTc-Fe3O4 were also investigated. Radiochemical analyses showed that the labeling efficiency was over 92% after 1 min in the presence of a reducing agent. Hydroxyl and amine groups covered the surface of the Fe3O4 particles. Therefore, 99Tc (VII) reduced to ...
Superconducting proximity devices using low-dimensional semiconducting elements enable a ballistic regime in the proximity transport. The use of topological insulators in such devices is considered promising owing to the peculiar transport properties these materials offer, as well the hope of inducing topological superconductivity and Majorana phenomena via proximity effects. Here we demonstrate the fabrication and superconducting properties of proximity Josephson devices integrating nanocrystals single of Bi2Te2.3Se0.7 with a thickness of a few unit cells. Single junctions display typical characteristics of planar Josephson devices; junctions integrating two nanocrystals behave as nanodimensional superconducting quantum interference devices. A peculiar temperature and magnetic field evolution of the Josephson current along with the observed excess current effect point towards the ballistic proximity regime of topological channels. This suggests the proposed devices are promising for testing topological
In this work the magnetic anisotropies of the diluted magnetic semiconductor (Ga,Mn)As were investigated experimentally. (Ga,Mn)As films show a superposition of various magnetic anisotropies which depend sensitively on various parameters such as temperature, carrier concentration or lattice strain. However, the anisotropies of lithographically prepared (Ga,Mn)As elements differ significantly from an unpatterned (Ga,Mn)As film. In stripe-shaped structures this behaviour is caused by anisotropic relaxation of the compressive lattice strain ...
An inevitable complication of blood transfusions is iron overload. Assessment of iron overload by serum ferritin is widely used, relatively easy to perform and most acceptable, but ferritin fluctuates with infection and inflammation. Therefore, serial measurements and trend of serum ferritin values should be considered.. Assessment of liver iron concentration (LIC) by liver biopsy is invasive and cannot be performed repeatedly. Superconducting Quantum Interference Device (SQUID) measures LIC accurately. There are only few SQUID machines available worldwide as it is an expensive equipment to purchase and maintain.. Recently, magnetic resonance imaging (MRI) using T2* and R2* relaxation parameters has been used to quantitatively assess iron overload in liver and heart. Cardiac T2* value ,20 milliseconds and liver T2* value, 6.3 milliseconds indicate iron overload.. ...
In ultra-low field nuclear magnetic resonance (ULF-NMR) with strong prepolarization field (B{sub p}), type-II superconducting pick-up coils may be vulnerable to flux pinning from the strong B{sub p}. Pick-up coils made of NbTi, Nb, and Pb were evaluated in terms of acquired NMR signal quality. The type-II pick-up coils showed degraded signals above 61 mT maximum exposure, while the Pb pick-up coil exhibited no such degradation. Furthermore, a negative counter pulse following a strong B{sub p} was shown to follow magnetic hysteresis loop to unpin the trapped flux in the type-II pick-up coil and restore the NMR signal. ...

According to the shell model, protons or neutrons tend to form pairs of opposite total angular momentum. Therefore, the magnetic moment of a nucleus with even numbers of each protons and neutrons is zero, while that of a nucleus with an odd number of protons and even number of neutrons (or vice versa) will have to be that of the remaining unpaired nucleon. For a nucleus with odd numbers of each protons and neutrons, the total magnetic moment will be some combination of the magnetic moments of both of the last, unpaired proton and neutron. The magnetic moment is calculated through j, l and s of the unpaired nucleon, but nuclei are not in states of well defined l and s. Furthermore, for odd-odd nuclei, there are two unpaired nucleons to be considered, as in deuterium. There is consequently a value for the nuclear magnetic moment associated with each possible l and s state combination, and the actual state of the nucleus is a superposition of these. Thus the real (measured) nuclear magnetic ...

Magnetic micro-robots are small robots under 1mm in size, made of magnetic materials, with relatively simple structures and functionalities. Such micro-robots can be actuated and controlled remotely by externally applied magnetic fields, and hence have the potential to access small and enclosed spaces. Most of the existing magnetic micro-robots can operate in wet environments. When the robots are actuated by the applied magnetic field to move inside a viscous liquid, they invoke flow motions around them inside the liquid. The induced flows are relatively local as the velocity of these flows decays rapidly with the distance from a moving robot, and the flow patterns are highly correlated with the motions of the micro-robots which are controllable by the applied magnetic field. Therefore, it is possible to generate local flow patterns that cannot be easily done using other microfluidic techniques. In this work we propose to use rotational motion of the magnetic micro-robots for local manipulation of flows

Apparatus for making biomagnetic measurements includes a biomagnetometer for measuring magnetic fields produced by the body and an electromagnetic location measurement and recording system for automatically determining the location of the portion of the body from which the magnetic signals are being gathered. The electromagnetic location recording system permits establishing a real time body frame of reference with respect to the biomagnetometer, so that biomagnetic signals can be correlated directly with body location and structure. The electromagnetic location recording system may be operated continuously at radiation wavelengths which do not interfere with the taking of data, or intermittently with the taking of biomagnetic data, to avoid interference with the measured values of the biomagnetic data. The elements of the electromagnetic location recording system have substantially no residual magnetism when the location recording system is not operating, as the biomagnetic signals are typically so

The continuous wave (CW) EPRI technique, in particular, has been widely used in a variety of applications in the fields of biology and medicine due to its high sensitivity and applicability to a wide range of free radicals and paramagnetic species. However, the technique requires long image acquisition periods, and this limits its use for many in vivo applications where relatively rapid changes occur in the magnitude and distribution of spins. Therefore, there has been a great need to develop fast EPRI techniques. We report the development of a fast 3D CW EPRI technique using spiral magnetic field gradient.

A magnetic separator for isolating magnetically-labeled substances of interest, such as immunological agents, from a non-magnetic test medium using a method of high gradient magnetic separation. The target substance is contacted with microscopic magnetic particles having a receptor for binding with the target substance. The test medium containing the magnetic particles is held in a non-magnetic container and placed into a gap within an arrangement of magnets for causing the magnetic particles to adhere to selected locations upon the interior wall of the container. The quantity of magnetic particles may be controlled to cause the magnetic particles collected upon the interior wall to form a monolayer. The magnets are arranged upon a yoke which may provide linear, surrounding multipolar, or partially surrounding multipolar configurations of magnetic pole faces about the gap. The magnetic pole faces may be of differing cross-sectional areas to enhance the magnetic field gradient in regions adjacent to the

The WT3000E can be used to evaluate magnetic materials. Energy loss due to hysteresis characteristics or over currents occurring in iron cores is called core loss or iron loss. Measurements of iron loss using an Epstein device can be taken as-is because power calculated from secondary coil voltage and primary coil current does not include copper loss. The WT3000E can measure it accurately when a drive frequency of the power supply is much higher than commercial frequency. Also, if you input frequency, cross-sectional area, and other parameters, you can calculate the magnetic flux density B and AC magnetic field H using user-defined functions and display the results on screen of the WT3000E. ...

Overall, three main findings emerged. (i) Pigeons can discriminate magnetic compass directions with the left as well as the right eye. This suggests processing of magnetic compass information by either brain hemisphere. (ii) Brain systems associated with the left and the right eye seem to process magnetic cues differently. (iii) Regarding the correct detection of the goal direction, the right eye (left hemisphere) is superior, as in most other cases studied so far.. The first important finding is that pigeons are capable of magnetic compass orientation with the left as well as the right eye and, consequently, with both brain hemispheres. This contrasts with the findings in European robins (Wiltschko et al. 2002), silvereyes (Wiltschko et al. 2003) and domestic chicks (Rogers et al. 2008), but is in line with the recent findings in garden warblers (Hein et al. in press). Interestingly, Rogers et al. (2008) considered the possibility that either brain hemisphere of chicks might, in principle, be ...
Magnetofection is a combination of the words magnet and transfection. Transfection is a process by which genetic material may be introduced into the target cell in order to reach the nucleus and be expressed. The term magnet is used to describe the process of transfection since it makes use of magnetic fields to enable it. Transfection can be done in various ways. It can be mediated using specific chemicals such as calcium phosphate, cationic liposomes, and dendrimers. It can also be through physical means such as magnetofection. Magnetofection is a method that attempts to improve the efficiency of delivery methods. It also prevents toxicity, which is the disadvantage of chemical-based transfection methods. In magnetofection, the nucleic acids need to be associated first with magnetic nanoparticles so that when magnetic force is applied the nucleic acid complex will be driven into the target cell.1 Magnetofection can be used to deliver all types of nucleic acids, such as DNA, siRNA, dsRNA, ...

It represents the extent to which a specimen is magnetised when placed in a magnetising field.. Or in other words the intensity of magnetisation of a magnetic material is defined as the magnetic moment per unit volume of the material.. M = Magnetic moment/volume = μM / V …1. Let a = Uniform area of cross-section of the magnetised specimen.. l = magnetic length of the specimen.. m = strength of each pole of the specimen,. As μm = ml. and V = al. then equation (1) becomes. M = m x 2l / a x 2l. or M = m/a. thus intensity of magnetisation of a magnetic material is also defined as the pole strength per unit area of cross-section of the material..

In accordance with the present invention, ferromagnetic thin films of iron that have reduced relaxation rates and methods of making the same are provided. It should be noted that pure iron is a ferromagnet (i.e., has a spontaneous magnetization alignment) with the lowest intrinsic damping rate of all of the ferromagnets. The present invention provides a ferromagnetic structure comprising a substrate and a ferromagnetic thin film of iron (Fe) formed on the substrate. An element selected from the group consisting of titanium (Ti), vanadium (V), chromium (Cr), and manganese (Mn) (i.e., a lower-Z transition metal element) is alloyed with the ferromagnetic thin film of iron to reduce the relaxation rate of the ferromagnetic thin film.
Spin-torque transfer (STT) effects have brought spintronics ever closer to practical electronic applications, such as MRAM and active broadband microwave spin-torque oscillator (STO), and have emerged as an increasingly attractive field of research in spin dynamics. Utilizing materials with perpendicular magnetic anisotropy (PMA) in such applications offers several great advantages such as low-current, low-field operation combined with high thermal stability. The exchange coupling that a PMA thin film exerts on an adjacent in-plane magnetic anisotropy (IMA) layer can tilt the IMA magnetization direction out of plane, thus creating a stack with an effective tilted magnetic anisotropy. The tilt angle can be engineered via both intrinsic material parameters, such as the PMA and the saturation magnetization, and extrinsic parameters, such as the layer thicknesses.. STOs can be fabricated in one of a number of forms-as a nanocontact opening on a mesa from a deposited pseudospin-valve (PSV) structure, ...

As a result, the distribution of current source changes in the affected area of the ...
Especially during interventions realised in open magnetic resonance scanners the medical stuff is exposed to strong static magnetic fields. It is necessary to ensure that the performance of the medical stuff is not impaired due to exposure and does not pose a risk for the patients. This topic was investigated in the project Effects of Exposure to Strong Static Magnetic Fields on the Cognitive Performance of Volunteers. Several subjects reported predominantly at seven Tesla and during movement in magnetic field gradients vertigo, nystagmus, magnetophosphenes and head ringing. Nevertheless, the annoying perceptions did not have any influence on the cognitive performance of volunteers. Most of them got quickly accustomed to the exposure and the symptoms disappeared. The magnetic field had no influence on stress hormone level in saliva and blood. ...

A method for manipulating domain pinning and reversal in a ferromagnetic material comprises applying an external magnetic field to a uniaxial ferromagnetic material comprising a plurality of magnetic domains, where each domain has an easy axis oriented along a predetermined direction. The external magnetic field is applied transverse to the predetermined direction and at a predetermined temperature. The strength of the magnetic field is varied at the predetermined temperature, thereby isothermally regulating pinning of the domains. A magnetic storage device for controlling domain dynamics includes a magnetic hard disk comprising a uniaxial ferromagnetic material, a magnetic recording head including a first magnet, and a second magnet. The ferromagnetic material includes a plurality of magnetic domains each having an easy axis oriented along a predetermined direction. The second magnet is positioned adjacent to the magnetic hard disk and is configured to apply a magnetic field transverse to the
As in many other studies reported, rat was also used as a model in this study [1, 6, 8-10]. The advantages include easy manipulation, maintenance and adaptation to the objectives of the study. Other animals have been used, such as rabbits [7, 11, 12] or dogs [13].. This experimental study was based on investigations reported by Brighton (apud Christian) [14]; Burkitt, Young and Heath [15]; Hunter (apud Christian) [14]; and Lane and Davis (apud Christian) [14]. The surgically prepared bone cavity presented only one ruptured cortical, maintaining thus the reproducibility of a fixed fracture [16].. The metallic washers were attached to the bone structure with titanium screws. Biocompatibility of titanium with the spongeous medullary area has already been shown by Veeck, Puricelli and Souza [1]. Due to technical difficulties, the stainless steel washers were not protected against corrosion, differing thus from those used by Lemons and Natiella [17]. Martensitic stainless steel relates to the ...

PY - 2010/12/1. Y1 - 2010/12/1. N2 - A method involving the use of magnetic nanoparticles to suppress the cross-reactions in immunoassay is developed. Antibodies are coated onto magnetic nanoparticles. These antibodies bind with target and non-target molecules. Once an alternative-current magnetic field is applied, magnetic nanoparticles oscillate with the magnetic field. The target and non-target molecules attached onto magnetic nanoparticles via antibodies experience a centrifugal force, which is against the association between antibodies and target/non-target molecules. Theoretically, the centrifugal force is proportional to the square of the frequency of the applied magnetic field. Thus, the strength of the centrifugal force can be manipulated by changing the frequency of the applied magnetic field. By ...
The effects of different spin orientations on transport through carbon nanotubes are studied, using a simple tight-binding model within the mean-field approximation. It turns out that, in the absence of external magnetic field, the mean-field ground states of both semiconducting and metallic nanotubes are antiferromagnetic. As regards electronic/transport properties, it is observed that the conductance characteristics of spin-up and spin-down carriers are separated, and a negative differential resistance (NDR) feature in the I-V characteristics is detected, when the system is subjected to external magnetic field. NDR is particularly interesting for a wide range of applications ...

The antiferromagnetic (Cr 2 O 3 ) domain wall velocity was estimated by a quasi-static approach using a pulsed voltage. At a pulse voltage amplitude of -12 V, corresponding to an electric field of -8.0 × 10 2 kV/cm, the domain wall velocity was very low, at 0.3 m/s. The domain wall velocity increased with increasing voltage amplitude, reaching 22 m/s at -20 V (-1.3 × 10 3 kV/cm). The change in the domain wall velocity with the applied voltage amplitude indicates the creep motion of the domain wall. ...

Finally, we show that a quantitative comparison with experimental data requires the proper inclusion of excitonic effects ...
For spin 1/2 nuclei, the energy difference between the two spin states at a given magnetic field strength are proportional to their magnetic moments. However, even if all protons have the same magnetic moments, they do not give resonant signals at the same field/frequency values. This is because this dependent on the electrons surrounding the proton in covalent compounds. Upon application of an external magnetic field, these electrons move in response to the field and generate local magnetic fields that oppose the much stronger applied field. This local field thus shields the proton from the applied magnetic field, which must therefore be increased in order to achieve resonance (absorption of rf energy). Such increments are very small, usually in parts per million (ppm). The difference between 2.3487T and 2.3488T is therefore about 42ppm. However a frequency scale is commonly used to designate the NMR signals, even though the spectrometer may operate by sweeping the magnetic field, and thus ...
New measurements of atomic-scale magnetic behavior in iron-based superconductors by researchers at the Department of Energys Oak Ridge National Laboratory and Vanderbilt University are challenging conventional wisdom about superconductivity and magnetism.. The study published in Advanced Materials provides experimental evidence that local magnetic fluctuations can influence the performance of iron-based superconductors, which transmit electric current without resistance at relatively high temperatures.. In the past, everyone thought that magnetism and superconductivity could not coexist, said ORNLs Claudia Cantoni, the studys first author. The whole idea of superconductors is that they expel magnetic fields. But in reality things are more complicated.. Superconductivity is strongly suppressed by the presence of long-range magnetism -- where atoms align their magnetic moments over large volumes -- but the ORNL study suggests that rapid fluctuations of local magnetic moments have a ...

The azimuthal angular dependence of the vectorial hysteresis loops in the Fe50Mn50(AF)/Ni81Fe19(F) bilayer grown under a magnetic field was investigated using a combination of vectorial magneto-optic Kerr effect and model calculation. From a comparison of the experimental and calculation results, it is found that the AF easy axis is not parallel with but rotated by about 20° away from the applied magnetic field during the sample growth. Moreover, the transverse loop at the AF easy axis does not vanish but displays an open full circle (i.e., magnetization changes sign between decreasing and increasing field branches for the full hysteresis measurement). Our model calculation reveals that they are reminiscent of the non-collinear uniaxial and unidirectional anisotropies. Specifically, the angular dependence of the transverse hysteresis is well reproduced with our model calculation taking non-collinear magnetic anisotropies into account. Coercivity determined from the longitudinal loops, on the ...

AU - Yoshioka, Naoki. PY - 2005/1/24. Y1 - 2005/1/24. N2 - A novel stable organic radical, 2,2-diphenyl-1,2-dihydrobenzo[g]quinoline- N-oxyl (2), has been synthesized and structurally characterized in order to examine the ring extension effect on the known derivative, 2,2-diphenyl-1,2- dihydroquinoline-N-oxyl (1). Based on SQUID measurement, 2 exhibited a ferromagnetic interaction obeying the Bleaney-Bowers equation with 2J = +4.6 cm -1. The X-ray analysis revealed an intermolecular edge-edge association of the aryl ring and N-oxyl moiety in the crystal of 2. The bifurcated edge-edge contacts between the α-spin site (nitroxyl O atom) and the β-spin site (aryl-H atoms) are responsible for the ferromagnetic interaction of 2..

N2 - Crystallographic structures and magnetic properties of chemically synthesized FePt nanoparticles, which were firmly stabilized into a monolayer on thermally oxidized Si substrate using 3-amino propyldimethylethoxysilene, were studied. The two-dimensional structure of FePt nanoparticles was confirmed by plan-view high-resolution scanning microscopy observation. The particles transformed from fcc to highly ordered L10 structure by annealing at 800°C under high vacuum with minimal coalescence. From rotational hysteresis loss analysis, a large magnetic anisotropy field of over 80kOe for the 800°C-annealed film was estimated. The coercivity of the ...
Magnetism is a class of physical phenomena that includes forces exerted by magnets on other magnets. It has its origin in electric currents and the fundamental magnetic moments of elementary particles. These give rise to a magnetic field. A magnetic field is a region of space near a magnet, electric current, or moving charged particle in which a magnetic force acts on any other magnet, electric current, or moving charged particle. All materials are influenced to some extent by a magnetic field. Large objects, such as the earth, other planets, and stars, also produce magnetic fields. - Stock Image C022/1932
The researchers discovered that the velocity of the motion of domain walls is always oscillating. This is a new effect that could prove to be useful in the future, said Dr. André Bisig, lead author of the paper Correlation between spin structure oscillations and domain wall velocities, which has recently been published in Nature Communications. It was also found that the applied method is very effective in reliably moving the domain walls at very high velocities. The faster we move the domain wall, the easier it is to control it, said Bisig. Another observation concerns the effects associated with irregularities or defects in the nanowires. According to the results, these effects only become noticeable when domain walls are moving slowly. The faster a domain wall spins, the less relevant is the role played by defects in the material. While theoretical research concerns itself principally with observing domain wall velocity and its correlation with oscillations in the spin structure, the ...
Zinc substituted cobalt ferrite nanoparticles (CoxZn1-xFe2O4, with x = 0.0, 0.2, 0.4, 0.8 and 1.0) were prepared via sol-gel route and the effect of zinc concentration on saturation magnetization and lattice parameter were investigated. The particle sizes of the as obtained samples were found to be ~10 nm which increases upto ~92 nm on annealing at 1000oC. The frequency bands near 564-588 cm-1 and 425-442 cm-1 are assigned to the tetrahedral and octahedral clusters which confirm the presence of M-O stretching band in ferrites. The unit cell parameter a increases linearly with increasing concentration of zinc due to larger ionic radii of Zn2+ ion . It was found that this substitution allows tunable changes in the magnetic properties of cobalt ferrite. Interestingly, saturation magnetization first increases upto x = 0.4 and then decreases for higher Zn substitution, thus tunable changes in magnetic properties of cobalt ferrite are possible. Source of such behaviour could be the variation of exchange
The summation method allows the calculation of both the magnetization and the static magnetic field of a setup of conductive and ferromagnetic materials. T

We interpret the antiresonances in the transmission as either multipath zeroes resulting from ...
The source of magnetism is moving charge. When a material is magnetic, it means that it is capable of being magnetized, or able to attract a magnet. Ferromagnetism is a form of magnetism in which a substance tends to take a position with the magnetic axis parallel to the lines in a magnetic field. A ferromagnetic material is a substance that is able to become highly magnetic in a relatively weak magnetic field. A paramagnetic material is a substance whose ability to become magnetized is a little greater than a vacuum. A diamagnetic material is a substance that is repelled by a magnet because the atoms take a position at right angles to the lines of force of a magnet.. The Curie temperature is an essential temperature for a ferromagnetic material. For example, if a ferromagnetic material has a temperature under its Curie temperature, then the material has a net spontaneous magnetization, which means that the material becomes ferromagnetic, or magnetic. If a ferromagnetic material has a ...

Chromosomes were isolated from Chinese hamster x human hybrid cell lines containing four and nine human chromosomes. Human genomic DNA was biotinylated by nick translation and used to label the human chromosomes by in situ hybridization in suspension. Streptavidin was covalently coupled to the surface of magnetic beads and these were incubated with the hybridized chromosomes. The human chromosomes were bound to the magnetic beads through the strong biotin-streptavidin complex and then rapidly separated from nonlabeled Chinese hamster chromosomes by a simple permanent magnet. The hybridization was visualized by additional binding of avidin-FITC (fluorescein) to the unoccupied biotinylated human DNA bound to the human chromosomes. After magnetic separation, up to 98% of the individual chromosomes attached to magnetic beads were classified as human chromosomes by fluorescence microscopy. ...
A general theory of radio propagation by wave-guide modes is given, which simultaneously makes allowance for the gradualness of the lowest part of the ionosphere, the earths curvature and the earths magnetic field. The method involves solving differential equations satisfied by the matrix admittance or matrix reflexion coefficient variables. The mode condition, excitation factor, and polarization of the waves in a mode are derived by evaluating the residues of a series of poles of a contour integral. The earths curvature is allowed for by the method of the modified refractive index, thus avoiding the use of cumbersome spherical wave functions. This also permits the replacement of a point source by a line source with consequent further simplification of the mathematics. Formulae are given which have been used for computations described elsewhere (Budden & Martin 1962; Martin 1961). ...

Issues associated with the exposure of patients to strong, static magnetic fields during magnetic resonance imaging (MRI) are reviewed and discussed. The history of human exposure to magnetic fields is reviewed, and the contradictory nature of the literature regarding effects on human health is described. In the absence of ferromagnetic foreign bodies, there is no replicated scientific study showing a health hazard associated with magnetic field exposure and no evidence for hazards associated with cumulative exposure to these fields. The very high degree of patient safety in strong magnetic fields is attributed to the small value of the magnetic susceptibility of human tissues and to the lack of ferromagnetic components in these tissues.. ...
We investigate the effect of lattice geometry on the magnetic anisotropy and transport properties of Ni80Fe20 antidot nanostructures. The structures were fabricated using deep ultra-violet lithography at 248nm exposure wavelength. For an antidot array with a square lattice, a fourfold magnetic anisotropy with alternating hard axis and easy axis every 45° was observed. The honeycomb and rhomboid antidot lattice, however, both show a sixfold anisotropy, conforming well to the symmetry of their respective lattices. The magnetic hysteresis and micromagnetic simulation of the spin states at remanence show that the magnetization reversal process is very sensitive to the lattice arrangement of the holes. From the magnetotransport measurements, both the current density distribution and the magnetoresistance behaviour are markedly dependent on the antidot lattice geometry, in agreement with our transport simulations. © 2006 IOP Publishing Ltd ...
