摘要:
A storage element includes a storage layer having a magnetization perpendicular to a layer surface and storing information according to a magnetization state of a magnetic material; a fixed magnetization layer having the magnetization as a reference of the information of the storage layer and perpendicular to the layer surface; an interlayer formed of a nonmagnetic material and interposed between the storage layer and the fixed magnetization layer; a coercive force enhancement layer adjacent to the storage layer, opposite to the interlayer, and formed of Cr, Ru, W, Si, or Mn; and a spin barrier layer formed of an oxide, adjacent to the coercive force enhancement layer, and opposite to the storage layer. The storage layer magnetization is reversed using spin torque magnetization reversal caused by a current in a lamination direction of a layer structure including the storage layer, the interlayer, and the fixed magnetization layer, thereby storing information
