Abstract:
1. A storage element comprising: a storage layer which has magnetization vertical to a film surface and of which the direction of magnetization changes corresponding to information; a magnetization fixed layer which has magnetization vertical to the film surface serving as a reference of information stored in the storage layer; and an insulating layer as a non-magnetic body which is provided between the storage layer and the magnetization fixed layer wherein the direction of magnetization of the storage layer changes by injecting spin-polarized electrons in the laminated direction of the layer structure having the storage layer, the insulating layer, and the magnetization fixed layer and then recording of information is performed on the storage layer, wherein the size of an effective demagnetizing field that the storage layer receives is configured to be smaller than a saturated magnetization amount of the storage layer, and wherein a ferromagnetic layer material constituting the storage layer has CoFeB as the base material and an anti-corrosive element is added to the base material.
