    摘要: According to one embodiment, a magnetoresistive element includes a stack and a pair of electrodes that allows electric current to flow through the stack in a direction perpendicular to a surface of the stack. The stack includes a cap layer, a magnetization pinned layer, a magnetization free layer provided between the cap layer and the magnetization pinned layer, a tunneling insulator provided between the magnetization pinned layer and the magnetization free layer, and a functional layer provided within the magnetization pinned layer, between the magnetization pinned layer and the tunneling insulator, between the tunneling insulator and the magnetization free layer, within the magnetization free layer, or between the magnetization free layer and the cap layer. The functional layer includes an oxide including at least one element selected from Zn, In, Sn and Cd and at least one element selected from Fe, Co and Ni.

    摘要: A strain sensor element comprises a laminated film which has a magnetic free layer, a spacer layer, and a magnetic reference layer. The free layer has a variable magnetization direction and a out-of-plane magnetization direction. The reference layer has a variable magnetization direction which is pinned more strongly than the magnetization of the free layer. The spacer layer provided between the free layer and the reference layer. A pair of electrodes is provided with a plane of the laminated film. A substrate is provided with either of the pair electrodes and can be strained. The rotation angle of the magnetization of the free layer is different from the rotation angle of the magnetization of the reference layer when the substrate is distorted. Electrical resistance is changed depending on the magnetization angle between the free layer and the reference layer, which allows the element to operate as a strain sensor.
