摘要：
A CPP-GMR spin valve having a CoFe/NiFe composite free layer is disclosed in which Fe content of the CoFe layer ranges from 20 to 70 atomic % and Ni content in the NiFe layer varies from 85 to 100 atomic % to maintain low Hc and λS values. A higher than normal Fe content in the CoFe layer improves the MR ratio by ≧16% compared with conventional CoFe/NiFe free layers in which the Fe content in CoFe is typically
