Nanoscale Thermal Phenomena in the Vicinity of Magnetic Nanoparticles in Alternating Magnetic Fields
In this paper we present the development of a magnetic moment reference material for low moment magnetic samples. We first conducted an inter-laboratory comparison to determine the most useful sample dimensions and magnetic properties for common instruments such as vibrating sample magnetometers (VSM), SQUIDs, and alternating gradient field magnetometers. The samples were fabricated and then me...
BACKGROUND Alternating hemiplegia of childhood is a very rare and serious neurodevelopmental syndrome; its genetic basis has recently been established. Its characteristic features include typically-unprovoked episodes of hemiplegia and other transient or more persistent neurological abnormalities. METHODS We used transcranial magnetic stimulation to assess the effect of the condition on motor...
Static and alternating magnetic field effects are introduced from the viewpoint of radical-radical interaction. Since the effect of magnetic field is much smaller than that of the electric field, the magnetic field dependence is a very sensitive measurement of the interaction between radicals. The low-field peak on the magnetic field effects and the spin-correlated radical pair polarization of ...
Analyses and measurements have shown anomalous behavior of ferrofluids in alternating and rotating magnetic fields, including flow reversals and negative magnetoviscosities as a function of magnetic field amplitude and frequency. These experiments measure the ferrofluid viscous torque on a rotating cylinder while varying the magnetic field amplitude and frequency, thereby confirming the strong ...
