摘要：
A free magnetic layer is a laminated body of a CO2MnZ alloy layer (Z is one or more elements selected from a group consisting of Al, Sn, In, Sb, Ga, Si, Ge, Pb, and Zn) and a CoaFe100-a alloy layer. The CoaFe100-a alloy layer has a composition ratio 76≦a≦100 or a face-centered cubic (fcc) structure, in which an equivalent crystal face expressed as a {111} plane is preferentially oriented in a direction parallel to a film surface, and the CoaFe100-a alloy layer is in contact with the nonmagnetic material layer.
