Abstract:
A storage element includes: a storage layer which retains information by a magnetization state of a magnetic substance; a magnetization pinned layer having magnetization which is used as the basis of the information stored in the storage layer; and an interlayer of a non-magnetic substance provided between the storage layer and the magnetization pinned layer. The storage element is configured to store information by reversing magnetization of the storage layer using spin torque magnetization reversal generated by a current passing in a laminate direction of a layer structure including the storage layer, the interlayer, and the magnetization pinned layer, and when the saturation magnetization of the storage layer and the thickness thereof are represented by Ms (emu/cc) and t (nm), respectively, (1489/Ms)−0.593
