Magnetic detecting element with diffusion-preventing layer between spacer Cu and magnetic layer, and method of manufacturing the same
There is provided a magnetic detecting element by devising a configuration of a free magnetic layer or a pinned magnetic layer, and a method of manufacturing a magnetic detecting element. The free magnetic layer is formed to have a three-layered structure of a CoMnZ alloy layer, a CoMnX alloy layer, and a CoMnZ alloy layer. The CoMnX alloy layer is formed of a metal compound whose compositional formula is represented by CoaMnbXc (X is one or more elements selected from a group of Ge, Sn, Ga, and Sb, a, b, and c are atomic percent, and a+b+c=100 atomic percent). The CoMnZ alloy layer is formed of a metal compound whose compositional formula is represented by CodMneZf (Z is Al or Si, d, e, and f are atomic percent, and d+e+f=100 atomic percent).
