Abstract
There is disclosed an information storage element including a first layer including a ferromagnetic layer with a magnetization direction perpendicular to a film face; an insulation layer coupled to the first layer; and a second layer coupled to the insulation layer opposite the first layer, the second layer including a fixed magnetization so as to be capable of serving as a reference of the first layer. The first layer is capable of storing information according to a magnetization state of a magnetic material, and the magnetization state is configured to be changed by a spin injection. A magnitude of an effective diamagnetic field which the first layer receives is smaller than a saturated magnetization amount of the first layer.
