Abstract:
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.
