    摘要: A magnetoresistance effect element includes: a first ferromagnetic layer having invariable magnetization perpendicular to a film plane; a second ferromagnetic layer having variable magnetization perpendicular to the film plane; a first nonmagnetic layer interposed between the first ferromagnetic layer and the second ferromagnetic layer; a third ferromagnetic layer provided on an opposite side of the second ferromagnetic layer from the first nonmagnetic layer, and having variable magnetization parallel to the film plane; and a second nonmagnetic layer interposed between the second and third ferromagnetic layers. Spin-polarized electrons are injected into the second ferromagnetic layer by flowing a current in the direction perpendicular to the film planes between the first and third ferromagnetic layers, precession movement is induced in the magnetization of the third ferromagnetic layer by injecting the spin-polarized electrons, and a microwave magnetic field of a frequency corresponding to the precession movement is applied to the second ferromagnetic layer.
