<P>PROBLEM TO BE SOLVED: To provide a storage element having excellent characteristic balance by ensuring thermal stability. <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 a 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 the storage layer changes thus recording the information in the storage layer. A lamination structure having a Co-Fe-B magnetic layer, and at least one non-magnetic layer, where an oxide layer, the Co-Fe-B magnetic layer and the non-magnetic layer are laminated sequentially, is formed in the storage layer. <P>COPYRIGHT: (C)2013,JPO&INPIT |
