Abstract:
A magnetization control element according to an aspect of the invention includes a magnetization control layer containing a magnetoelectric material exhibiting a magnetoelectric effect, and a magnetic coupling layer that is magnetically coupled to a magnetization of a first surface of the magnetization control layer through exchange coupling and exhibits a magnetic state according to the magnetization of the first surface, wherein a magnetization having a component in a direction opposite to a direction of a magnetization of the magnetic coupling layer is imparted to the magnetization control layer.
