Abstract:
A magnetic domain wall movement element includes a wiring layer containing a ferromagnetic material, a non-magnetic layer in contact with the first surface of the wiring layer, a first conductive layer connected to the first surface of the wiring layer and containing a ferromagnetic material; and a second conductive layer connected to the wiring layer at a distance from the first conductive layer. A first part of the connection face of the first conductive layer is directly connected to the wiring layer, and a second part of the connection face other than the first part is connected to the wiring layer via the non-magnetic layer.
