CPP magneto-resistive element, method of manufacturing CPP magneto-resistive element, magnetic head, and magnetic memory apparatus

摘要

A CPP magneto-resistive element includes a substrate and an antiferromagnetic layer, a fixed magnetic layer, a non-magnetic intermediate layer, and a free magnetic layer that are sequentially formed on the substrate, wherein the antiferromagnetic layer includes an alloy of Mn and at least one element of a group including Pd, Pt, Ni, Ir, and Rh, wherein the specific resistance of the antiferromagnetic layer ranges from 10 muOmega.cm to 150 muOmega.cm at a temperature of 300 K.
