Abstract
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.
