Abstract:
A storage element includes: a storage layer configured to retain information based on a magnetization state of a magnetic material and include a perpendicular magnetization layer whose magnetization direction is in a direction perpendicular to a film plane, a non-magnetic layer, and a ferromagnetic layer that has an axis of easy magnetization along a direction in the film plane and has a magnetization direction inclined to a direction perpendicular to the film plane by an angle in a range from 15 degrees to 45 degrees, the storage layer being configured by stacking of the perpendicular magnetization layer and the ferromagnetic layer with intermediary of the non-magnetic layer and magnetic coupling between the perpendicular magnetization layer and the ferromagnetic layer; a magnetization pinned layer; and a non-magnetic intermediate layer.
