Abstract:
1. A magnetoresistance effect element comprising: a magnetoresistance effect film and a pair of electrodes electrically coupled to the magnetoresistance effect film; wherein the magnetoresistance effect film comprises: a first magnetic layer; a second magnetic layer; a nonmagnetic intermediate layer located between the first and second magnetic layers; and a film provided between the first magnetic layer and the nonmagnetic intermediate layer, the film having a magnetization, wherein a thickness of the film is not larger than 3 nanometers, the electrodes electrically coupled to the magnetoresistance effect film are configured to supply a sense current perpendicularly to a film plane of the magnetoresistance effect film, a direction of a magnetization of the first magnetic layer is pinned, and a direction of the magnetization of the film is pinned, wherein a mean thickness of the film is in a range between one atomic layer and three atomic layers.
