Claim Text:
1. An information storage element comprising: a first layer including a ferromagnetic layer with a magnetization direction perpendicular to a film face and including Co, Fe, and B; 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 and having a magnetization direction perpendicular to the film face, wherein 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, wherein a magnitude of an effective diamagnetic field which the first layer receives is smaller than a saturated magnetization amount of the first layer, wherein each of the first layer, the insulation layer and the second layer are free of a magnetization parallel to the film face, and wherein a composition of the Co—Fe—B is (Co and, 0≦x≦40, 60≦y≦100, and 20<z≦40.
