Abstract:
1. A storage element comprising: a storage layer that holds information according to a magnetization state of a magnetic body, the storage layer having a diameter of 30 nm to less than 45 nm; a magnetization fixing layer that has magnetization serving as a reference of the information stored in the storage layer; and an insulation layer that is formed of a non-magnetic body disposed between the storage layer and the magnetization fixing layer, wherein the information is stored by reversing the magnetization of the storage layer using spin torque magnetization reversal occurring with a current flowing in a lamination direction of a layer configuration of the storage layer, the insulation layer, and the magnetization fixing layer, and a size of the storage layer is less than a size in which a direction of the magnetization is simultaneously changed.
