Title:
MAGNETIZATION CONTROL ELEMENT, MAGNETIC MEMORY, AND MAGNETIC RECORDING SYSTEM
Document Type and Number:
WIPO Patent Application WO/2018/194155
Kind Code:
A1
Abstract:
A magnetization control element (100) according to an embodiment of the present invention is provided with: a magnetization control layer (10) which includes a magnetoelectric material exhibiting a magnetoelectric effect; and a magnetic coupling layer (20) which is magnetically coupled with a magnetization (M10a) of a first surface (10a) of the magnetization control layer by exchange coupling, and which exhibits a magnetization state (M20) corresponding to the magnetization of the first surface. The magnetization control layer is provided with a magnetization (Madd) having a component of an opposite direction from the orientation of magnetization of the magnetic coupling layer.
