Abstract:
1. A magnetoresistive effect element comprising: a magnetoresistive effect film including a magnetization-pinned layer having a magnetic film whose direction of magnetization is pinned substantially in one direction, a magnetization free layer having a magnetic film whose direction of magnetization varies in response to an external magnetic field, a nonmagnetic metallic intermediate layer interposed between said magnetization-pinned layer and said magnetization free layer, and a resistance adjustment layer interposed between said magnetization-pinned layer and said magnetization free layer and solely composed of Sb; and a pair of electrodes electrically coupled to said magnetoresistive effect film to supply a sense current substantially vertically of the film plane of said magnetoresistive effect film, wherein a thickness of said resistance adjustment layer is equal to or less than 1 nm.
