Abstract:
1. A memory element, comprising: a layered structure including, a memory layer that has a magnetization perpendicular to a film face and a magnetization direction that varies corresponding to information, a magnetization-fixed layer that has a magnetization indirection perpendicular to the film face and becomes a reference for the information stored in the memory layer, an insulating layer provided between the memory layer and the magnetization-fixed layer and formed of a non-magnetic material, and a cap layer provided at a face side opposite to the insulating layer-side face of the memory layer, wherein: an electron that is spin-polarized is injected in a lamination direction of the layered structure, 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 at least a face of the cap layer that comes into contact with the memory layer is formed of a Ta film.
