Modulation of Auditory Evoked Magnetic Fields by Benzodiazepines

Neuropsychobiology, 1986
The N1 and P2 components of the auditory evoked magnetic field were shown to be modified by the benzodiazepines diazepam and triazolam. Previous studies indicate that the electrical sources of these components are located in the auditory cortex, implying that benzodiazepines have a direct or indirect effect on neuronal activity at this level.

Magnetooptical Recording with Optical Modulation and Magnetic Field Modulation

IEEE Translation Journal on Magnetics in Japan, 1991
The magnetooptic recording characteristics of three types of DyFeCo films with a quadrilayer structure were measured using three recording methods: optical modulation, magnetic field modulation and the laser-off method. In the laser-off method, the laser power was lowered only while the magnetic field was changing. The transition metal (TM)-rich medium

AC photovoltaic module magnetic fields

Conference Record of the Twenty Sixth IEEE Photovoltaic Specialists Conference - 1997, 2002
Implementation of alternating current (AC) photovoltaic (PV) modules, particularly for distributed applications such as PV rooftops and facades, may be slowed by public concern about electric and magnetic fields (EMF). This paper documents magnetic field measurements on an AC PV module, complementing EMF research on direct current PV modules conducted ...

The Magnetic Phase Transition of FeRh Modulated by AC Magnetic Field

physica status solidi (RRL) – Rapid Research Letters, 2022
It is well known that CsCl‐type FeRh undergoes from antiferromagnetic (AFM) to ferromagnetic (FM) phase transition near room temperature with large thermal hysteresis. Therefore, it is particularly essential to find new methods to manipulate the magnetic order of FeRh and reduce thermal hysteresis.

Amplitude Stabilizer for Magnetic Field Modulators

Review of Scientific Instruments, 1968
It is desirable to stabilize the amplitude and phase of magnetic field modulation applied to dc swept laboratory magnets for better approximation of true line shape, when large sweeps affect modulation coil impedance along with magnet yoke permeability.

Modulation of the Magnetic Adlayer by External Field

Journal of the Physical Society of Japan, 1993
A model which simulates a system of magnetic-atom chain adsorbed on a crystal surface is proposed. The present model differs from the conventional Frenkel-Kontorova model at the point that each atom in the adlayer chain is magnetic and the strength of the exchange interaction between the nearest neighbor adatoms varies with the distance between the two

Transport in a magnetic field modulated graphene superlattice

Journal of Physics: Condensed Matter, 2009
Using the transfer matrix method, we study the transport properties through a magnetic field modulated graphene superlattice. It is found that the electrostatic barrier, the magnetic vector potential, and the number of wells in a superlattice modify the transmission remarkably.

Electric field modulation of magnetic exchange in molecular helices

Nature Materials, 2019
The possibility to operate on magnetic materials through the application of electric rather than magnetic fields-promising faster, more compact and energy efficient circuits-continues to spur the investigation of magnetoelectric effects. Symmetry considerations, in particular the lack of an inversion centre, characterize the magnetoelectric effect.

Excitation of Magnetization Using a Modulated Radiation Damping Field

The Journal of Physical Chemistry B, 2006
In this work, pulsed-field gradients are used to modulate the radiation damping field generated by the detection coil in an NMR experiment in order that spins with significantly different chemical shifts can affect one another via the radiation damping field.

Magnetic-field modulation of surface plasmon polaritons on gratings

Optics Letters, 2010
The propagation of surface plasmon polaritons (SPPs) on gratings can be experimentally modified when magneto-optically active materials are used. We have observed this effect in Au-Co thin-film bilayers where a polymer grating was patterned on the upper surface.
