    摘要: According to one embodiment, a magnetoresistive element includes the following configuration. A first magnetic layer has an invariable magnetization. A second magnetic layer has a variable magnetization. A nonmagnetic layer is provided between the first and the second magnetic layers. The first magnetic layer has a structure in which first, second and third magnetic material films and a nonmagnetic material film are stacked. The first magnetic material film is provided in contact with the nonmagnetic layer, the nonmagnetic material film is provided in contact with the first magnetic material film, the second magnetic material film is provided in contact with the nonmagnetic material film, and the third magnetic material film is provided in contact with the second magnetic material film. The second magnetic material film has a Co concentration higher than that of the first magnetic material film.

    摘要: According to one embodiment, a magnetoresistive element includes first, second and third magnetic layers, and first and second nonmagnetic layers. The third magnetic layer has stack layers including a first stack layer close to the second magnetic layer, and a second stack layer far from the second magnetic layer. Each of the first and second stack layers includes a first layer made of a ferromagnetic material and a second layer made of a nonmagnetic material, and a first ratio of a film thickness of the first layer to that of the second layer in the first stack layer is higher than a second ratio of a film thickness of the first layer to that of the second layer in the second stack layer.
