Abstract:
A memory includes an underlying layer of a ferromagnetic body, a first nonmagnetic layer on the underlying layer, a data memorizing layer laid on the first nonmagnetic layer and made of a ferromagnetic body having perpendicular magnetic anisotropy, a reference layer coupled through a second nonmagnetic layer with the data memorizing layer, and first and second magnetization fixed layers laid underneath the underlying layer to come into contact with the underlying layer. The data memorizing layer includes a magnetization liberalized region having reversible magnetization, and overlapping with the reference layer, a first magnetization fixed region coupled with an end of the magnetization liberalized region, and having a magnetization direction fixed to +z direction by the first magnetization fixed layer, and a second magnetization fixed region coupled with a different end of the magnetization liberalized region, and having a magnetization direction fixed to −z direction by the second magnetization fixed layer.
