Abstract
Electronic devices that incorporate magnetism, called spintronic devices, can increase the functionality of electronic circuits and lead to increases in efficiency. Such devices are useful if the magnetization can be manipulated electrically rather than by magnetic fields. This review covers the materials, underlying physics, and applications involved in such manipulation, focusing on two control mechanisms. The first is control by manipulating the magnetization through its coupling to ferroelectric order and the second is control by spin-polarized currents manipulating the magnetization through the angular momentum flowing into it.
