Abstract
A magnetic domain wall movement element includes a magnetic recording layer which includes a ferromagnetic material; a non-magnetic layer which is laminated on the magnetic recording layer; and a magnetization reference layer which is laminated on the non-magnetic layer, in which the magnetic recording layer has a first ferromagnetic layer, a spacer layer, and a second ferromagnetic layer in order from the non-magnetic layer, a magnetization of the first ferromagnetic layer and a magnetization of the second ferromagnetic layer are antiferromagnetically coupled, and an electrical resistivity of the first ferromagnetic layer is higher than the electrical resistivity of the second ferromagnetic layer.
