摘要
A spin-orbit torque type magnetoresistance effect element including a magnetoresistance effect element having a first ferromagnetic metal layer with a fixed magnetization direction, a second ferromagnetic metal layer with a varying magnetization direction, and a non-magnetic layer sandwiched between the first ferromagnetic metal layer and the second ferromagnetic metal layer; and spin-orbit torque wiring that extends in a first direction intersecting with a stacking direction of the magnetoresistance effect element and that is joined to the second ferromagnetic metal layer; wherein the magnetization of the second ferromagnetic metal layer is oriented in the stacking direction of the magnetoresistance effect element; and the second ferromagnetic metal layer has shape anisotropy, such that a length along the first direction is greater than a length along a second direction orthogonal to the first direction and to the stacking direction.
