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.

摘要： A magnetic memory element includes a first magnetic layer, a second magnetic layer, a first intermediate layer, a first magnetic wire, a first input unit, and a first detection unit. The first magnetic layer has magnetization fixed. The second magnetic layer has magnetization which is variable. The first intermediate layer is between the first magnetic layer and the second magnetic layer. The first magnetic wire extends in a first direction perpendicular to a direction connecting from the first magnetic layer to the second magnetic layer and is adjacent to the second magnetic layer. In addition, write-in is performed by propagating a first spin wave through the first magnetic wire and by passing a first current from the first magnetic layer toward the second magnetic layer. Read-out is performed by passing a second current from the first magnetic layer toward the second magnetic layer.
