Title:
STORAGE ELEMENT, PRODUCTION METHOD THEREFOR, AND STORAGE DEVICE
Document Type and Number:
WIPO Patent Application WO/2016/139879
Kind Code:
A1
Abstract:
Provided are: a storage element wherein variation in inversion timing for spin torque inversion is suppressed effectively, thereby enabling a stable high-speed operation; a production method therefor; and a storage device. The storage element according to an embodiment of the present invention comprises a magnetized fixed layer, an intermediate layer, and a storage layer. The magnetized fixed layer, which is magnetized in an orthogonal orientation to a film surface, has a configuration wherein the magnetization direction is invariable. The intermediate layer, which contains a non-magnetic body, is disposed above the magnetized fixed layer. The storage layer comprises an outer peripheral portion magnetized in the orthogonal orientation to film surface, and a central portion formed by being enclosed by the outer periphery portion and having the magnetization inclined from the orthogonal orientation to the film surface. The storage layer, which is disposed so as to face the magnetized fixed layer while sandwiching therebetween the intermediate layer, has a configuration wherein the magnetization direction is variable.
