    摘要: A storage element includes a storage layer for holding information depending on a magnetization state of a magnetic material; and a magnetization fixed layer in which magnetization direction is fixed, that is arranged relative to the storage layer through a nonmagnetic layer. The magnetization direction of the storage layer is changed with application of an electric current in a laminating direction to enable information to be recorded to the storage layer. A plurality of magnetization regions respectively having magnetization components in laminating directions and having magnetizations in different directions from each other are formed in the magnetization fixed layer or on an opposite side of the magnetization fixed layer relative to the storage layer.

    摘要: A storage element includes a storage layer, a fixed magnetization layer, a spin barrier layer, and a spin absorption layer. The storage layer stores information based on a magnetization state of a magnetic material. The fixed magnetization layer is provided for the storage layer through a tunnel insulating layer. The spin barrier layer suppresses diffusion of spin-polarized electrons and is provided on the side of the storage layer opposite the fixed magnetization layer. The spin absorption layer is formed of a nonmagnetic metal layer causing spin pumping and provided on the side of the spin barrier layer opposite the storage layer. A direction of magnetization in the storage layer is changed by passing current in a layering direction to inject spin-polarized electrons so that information is recorded in the storage layer and the spin barrier layer includes at least a material selected from oxides, nitrides, and fluorides.

    摘要: A memory device is provided. The memory device includes a memory layer and a fixed-magnetization layer. The memory layer retains information based on a magnetization state of a magnetic material. The fixed-magnetization layer is formed on the memory layer through an intermediate layer made of an insulating material. The information is recorded on the memory layer with a change in a magnetization direction of the memory layer caused by injecting a spin-polarized electron in a stacked direction. A level of effective demagnetizing field, which is received by the memory layer, is smaller than a saturation-magnetization level of magnetization of the memory layer.
