Abstract
A potential barrier region is positioned in direct or indirect contact with a region containing a magnetic element. The region containing a magnetic body has a multi-layered structure in which two ferromagnetic layers are separated by a non-magnetic intermediate layer, for example. The potential barrier region may be composed of a metal layer and a semiconductor layer, for example, and a Schottky barrier is produced between them. Magnetization of the region containing a magnetic body is controlled by modulating the potential barrier of the potential barrier region by means of application of an electric field. By using at least one magnetization of the region containing a magnetic element, storage of information is effected.
