    摘要: According to one embodiment, a magnetic recording element includes a stacked body. The stacked body includes a first and a second stacked unit. The first stacked unit includes first and second ferromagnetic layers and a first nonmagnetic layer. The first nonmagnetic layer is provided between the first and second ferromagnetic layers. The second stacked unit is stacked with the first stacked unit and includes third and fourth ferromagnetic layers and a second nonmagnetic layer. The fourth ferromagnetic layer is stacked with the third ferromagnetic layer. The second nonmagnetic layer is provided between the third and fourth ferromagnetic layers. An outer edge of the fourth ferromagnetic layer includes a portion outside an outer edge of the first stacked unit in a plane. A magnetization direction of the second ferromagnetic layer is determined by causing a spin-polarized electron and a rotating magnetic field to act on the second ferromagnetic layer.

    摘要: A magnetic memory element includes a laminated construction of a first electrode, a first pinned layer, a first intermediate layer, a memory layer, a second intermediate layer, a second pinned layer and a second electrode, and a third electrode coupled to the first intermediate layer and not directly coupled to the memory layer. The magnetization directions of the first pinned layer, the second pinned layer, and the memory layer are parallel or antiparallel to each other. The magnetization direction of the memory layer takes a first direction when the current is passed with a first polarity so that the current flowing through the first pinned layer exceeds a first threshold. The magnetization direction of the memory layer takes a second direction when the current is passed with a second polarity so that the current flowing through the first pinned layer exceeds a second threshold.

    摘要: A magnetic cell includes: a first ferromagnetic layer whose magnetization is substantially fixed in a first direction; a second ferromagnetic layer whose magnetization is substantially fixed in a second direction opposite to the first direction; a third ferromagnetic layer provided between the first and the second ferromagnetic layers, a direction of magnetization of the third ferromagnetic layer being variable; a first intermediate layer provided between the first and the third ferromagnetic layers; and a second intermediate layer provided between the second and the third ferromagnetic layers. The direction of magnetization of the third ferromagnetic layer can be determined under an influence of spin-polarized electrons upon the third ferromagnetic layer by passing a current between the first and the second ferromagnetic layers.
