摘要
A magnetic domain wall (MDW) motion device. The MDW motion device may include a ferromagnetic layer with perpendicular magnetic anisotropy and non-magnetic metal layers extending parallel to and in contact with the ferromagnetic layer. The ferromagnetic layer may include first ferromagnetic regions, which are arranged in an extension direction of the ferromagnetic layer, and second ferromagnetic regions, which are provided between an adjacent pair of the first ferromagnetic regions. The first and second ferromagnetic regions may have spin torque coefficients of opposite signs, and an MDW positioned near an interface between the first and second ferromagnetic regions may be moved by an in-plane current flowing through the non-magnetic metal layer.
