摘要： A magnetic memory includes a first magnetic layer, a second magnetic layer, a third magnetic layer, a first intermediate layer, a second intermediate layer, an insulator film, and an electrode. The third magnetic layer is provided between the first magnetic layer and the second magnetic layer in a first direction being perpendicular to the plane of both the first magnetic layer and the second magnetic layer. The insulator film is provided on the third magnetic layer in a second direction perpendicular to the first direction. The electrode is provided on the insulator film so that the insulator is sandwiched between the third magnetic layer and the electrode in the second direction. In addition, a positive voltage is applied to the electrode and a first current passes from the first magnetic layer to the second magnetic layer, thereby writing information to the second magnetic layer.

The multilayer having a lamination direction thereof is formed on the substrate and includes a first ferromagnetic layer. The first ferromagnetic layer has magnetization whose direction is in the lamination direction. The detecting portion and the input portions are formed on the multilayer and separated from each other by a first nonmagnetic layer. In addition, a portion of an outer edge of the multilayer viewed from the lamination direction makes a portion of one ellipsoid. The detecting portion and one of the input portions are located on the long axis of the one ellipsoid. The portion of the one ellipsoid is located on a side of one of the input portions.
