Patent ID: 7933145

Claim:
A nonvolatile magnetic memory device comprising: a magnetoresistance effect element that includes (A) a layered structure having a recording layer, (B) a first wiring electrically connected to a lower part of the layered structure, (C) a second wiring electrically connected to an upper part of the layered structure, and (D) an interlayer insulation layer surrounding the layered structure, wherein the magnetoresistance effect element further includes a low Young modulus region having a Young modulus lower than a Young modulus of a material forming the interlayer insulation layer, the recording layer has an easy magnetization axis, and a hard magnetization axis orthogonal to the easy magnetization axis, when a magnetostriction constant λ of a material forming the recording layer is a positive value, the low Young modulus region is disposed in an extension region of the easy magnetization axis of the recording layer, and when the magnetostriction constant λ of the material forming the recording layer is a negative value, the low Young modulus region is disposed in an extension region of the hard magnetization axis of the recording layer.
