Patent ID: 8830735

Claim:
A magnetic memory, comprising: a magnetization fixed layer having perpendicular magnetic anisotropy, a magnetization direction of said magnetization fixed layer being fixed; an amorphous interlayer dielectric; an underlayer formed on upper faces of said magnetization fixed layer and said interlayer dielectric; and a data recording layer formed on an upper face of said underlayer and having perpendicular magnetic anisotropy, wherein said underlayer includes: a first underlayer formed in contact with the upper faces of said interlayer dielectric and said magnetization fixed layer; and a second underlayer formed on said first underlayer, wherein said second underlayer is non-magnetic, and wherein said first underlayer intrinsically exhibits ferromagnetism, while said first underlayer is formed with such a thickness that said first underlayer does not exhibit ferromagnetism in a portion of said first underlayer formed on said interlayer dielectric.
