Abstract:
1. A spin-injection magnetoresistance effect element comprising: (A) a magnetization reversal layer that has a first face and a second face opposite to the first face, and stores information; (B) a first magnetization reference layer that is disposed near one end of the magnetization reversal layer in a manner of facing the first face of the magnetization reversal layer with intermediary of a first nonmagnetic film between the first magnetization reference layer and the magnetization reversal layer, the first magnetization reference layer being magnetized in a first direction; (C) a second magnetization reference layer that is disposed near the other end of the magnetization reversal layer in a manner of facing the first face of the magnetization reversal layer and being separated from the first magnetization reference layer with intermediary of a second nonmagnetic film between the second magnetization reference layer and the magnetization reversal layer, the second magnetization reference layer being magnetized in a second direction that is the opposite direction of the first direction; (D) a first electrode that is electrically coupled to the first magnetization reference layer; (E) a second electrode that is electrically coupled to the second magnetization reference layer; and (F) a third electrode that is disposed in a manner of facing the second face of the magnetization reversal layer with intermediary of an insulating film between the third electrode and the magnetization reversal layer.
