<P>PROBLEM TO BE SOLVED: To provide a storage element having excellent characteristic balance by ensuring thermal stability regardless of the environmental temperature. <P>SOLUTION: The storage element includes a layer structure having a storage layer which has magnetization perpendicular to the film surface, and the orientation of magnetization that changes corresponding to the information, a magnetization fixed layer having magnetization perpendicular to a film surface becoming the reference of the information stored in the storage layer, and an intermediate layer of a non-magnetic material provided between the storage layer and the magnetization fixed layer. When current is fed in the lamination direction of the layer structure, the orientation of magnetization of the storage layer changes thus recording the information in the storage layer. The storage layer includes a magnetic layer having a positive magnetostriction constant, and a negative thermal expansion material layer is provided in addition to the layer structure. <P>COPYRIGHT: (C)2013,JPO&INPIT |
