Abstract:
1. A storage element, comprising: a storage layer which has magnetization vertical to a film surface and in which a direction of the magnetization is changed in correspondence to information; a magnetization fixing layer which has a fixed magnetization direction that is vertical to a film surface becoming a reference of the information stored in said storage layer, the magnetization fixing layer having a multilayered ferri-pin structure in which a plurality of magnetic layers are laminated one upon another through at least one non-magnetic layer; and an insulating layer made of a non-magnetic material and provided between said storage layer and said magnetization fixing layer, wherein the direction of the magnetization of said storage layer is changed by injecting spin-polarized electrons in a lamination direction of a layer structure having said storage layer, said insulating layer, and said magnetization fixing layer, thereby recording information in said storage layer, and a magnitude of an effective diamagnetic field which said storage layer receives is smaller than an amount of saturation magnetization of said storage layer.
