Abstract:
1. A magnetic random access memory of domain wall motion comprising: a magnetic recording layer being a ferromagnetic layer having perpendicular magnetic anisotropy; a pair of current supply terminals connected to said magnetic recording layer for supplying a current to said magnetic recording layer; and an anti-ferromagnetic layer being in contact with a first region of said magnetic recording layer, wherein said first region includes a part of a current supply region of said magnetic recording layer that is between said pair of current supply terminals, wherein said pair of current supply terminals includes a first current supply terminal and a second current supply terminal, wherein said first current supply terminal is connected to said first region, wherein said magnetic recording layer includes a second region whose magnetization direction is opposite to a magnetization direction of said first region, wherein said second current supply terminal is connected to said second region, wherein the anti-ferromagnetic layer is not provided on the second region.
