The simplest form of this phenomenon is anisotropic and is proportional to one plus quantity mu B squared.
Thermal assisted switching and spin torque transfer are two applications of this phenomenon. Half-metals exhibit a strong form of this effect due to vanishing spin down density. Microwaves tuned to the cyclotron harmonics of two dimensional electron gases can cause unusually strong oscillations in this phenomenon, One form of this phenomenon takes place between two ferromagnetic layers separated by a non-magnetic layer, and is central to the field of spintronics, such as in hard disk read heads. The simplest form of this phenomenon is anisotropic and is proportional to one plus quantity mu B squared. FTPE, name this phenonomenon in which an applied B field changes the conductivity of a metal.
Thermal assisted switching and spin torque transfer are two applications of this phenomenon.
