Using a magnetic state for storage has two major benefits: the magnetic polarization
does not leak away with time, so the information is stored even when the power is turned off, and switching the magnetic polarization
between the two states does not involve actual movement of electrons or atoms and therefore has no known wear-out mechanism.
In the present paper we have attempted to find out the expression for magnetic polarization
and susceptibility for the <100>,<110>,<100> + <111> and <110> + <111> models.
The angle between the device and the magnetic polarization
axis is represented by 64 sectors in a full 360-degree range.
The magnetic polarization
of the MO material is oriented perpendicularly to the film plane, a necessity for MO readout to work.
Typically, built-in magnetic polarization
, a characteristic of electrical steel, results in jerks at low speeds.
Clearly, any two dimensional wave can be decomposed to two electric and magnetic polarizations
