    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.

    摘要: According to one embodiment, a magnetoresistive element comprises a storage layer having perpendicular magnetic anisotropy with respect to a film plane and having a variable direction of magnetization, a reference layer having perpendicular magnetic anisotropy with respect to the film plane and having an invariable direction of magnetization, a tunnel barrier layer formed between the storage layer and the reference layer and containing O, and an underlayer formed on a side of the storage layer opposite to the tunnel barrier layer. The reference layer comprises a first reference layer formed on the tunnel barrier layer side and a second reference layer formed opposite the tunnel barrier layer. The second reference layer has a higher standard electrode potential than the underlayer.
