Review

Magnetoelectronics

Gary A. Prinz

An approach to electronics is emerging that is based on the up or down spin of the carriers rather than on electrons or holes as in traditional semiconductor electronics. The physical basis for the observed effects is presented, and the initial successful applications of this technology for information storage are reviewed. Additional opportunities for the exploitation of this technology, which are currently under study, are described.

The author is at the Naval Research Laboratory, Washington, DC 20375, USA.
