Abstract:
1. A magnetic memory element comprising: a magnetization recording layer configured to include a ferromagnetic layer with perpendicular magnetic anisotropy; and a magnetic tunneling junction section configured to be used for reading information in said magnetization recording layer, wherein said magnetization recording layer includes two domain wall moving areas, and wherein said magnetization recording layer includes: a first magnetization fixed area, a zero-th magnetization fixed area and a second magnetization fixed area, each configured to have magnetization which is fixed, a first domain wall moving area configured to be arranged between said first magnetization fixed area and said zero-th magnetization fixed area and have magnetization which enable to be switched, a domain wall being movable in said first domain wall moving area, and a second domain wall moving area configured to be arranged between said zero-th magnetization fixed area and said second magnetization fixed area and have magnetization which enable to be switched, a domain wall being movable in said second domain wall moving area.
