摘要

PROBLEM TO BE SOLVED: To provide an ST-MRAM element ensuring stable recording with a low current, while improving the TMR characteristics.SOLUTION: A storage element includes a layer structure having a storage layer 17 the orientation of magnetization of which is changed in response to information, a magnetization fixed layer 15 having magnetization perpendicular to a film surface becoming a reference of information stored in the storage layer 17, and an intermediate layer 16 of a nonmagnetic body provided between the storage layer 17 and the magnetization fixed layer 15. When a carbon is inserted into the intermediate layer 16 and a current is fed in the lamination direction of the layer structure, orientation of magnetization of the storage layer 17 changes, and information is recorded for the storage layer 17.
