Abstract:
1. A memory element, comprising: a memory layer that has a magnetization perpendicular to a film face and a magnetization direction thereof varies corresponding to information; a magnetization-fixed layer that has a magnetization that is perpendicular to the film face and becomes a reference of the information stored in the memory layer; and an insulating layer that is provided between the memory layer and the magnetization-fixed layer and is formed of a non-magnetic material, wherein an electron that is spin-polarized is injected in a lamination direction of a layered structure having the memory layer, the insulating layer, and the magnetization-fixed layer, and thereby the magnetization direction of the memory layer varies and a recording of information is performed with respect to the memory layer, a magnitude of an effective diamagnetic field which the memory layer receives is smaller than a saturated magnetization amount of the memory layer, and in regard to the insulating layer that comes into contact with the memory layer, and the other side layer with which the memory layer comes into contact at a side opposite to the insulating layer, at least an interface that comes into contact with the memory layer is formed of an oxide film.
