Abstract

A magnetic memory device contains a synthetic antiferromagnetic (SAF) structure that includes an antiferromagnetically coupled stack and a reference layer. The antiferromagnetically coupled stack contains plural multilayer stacks. Each multilayer stack contains at least one ferromagnetic material layer, a non-magnetic layer and a non-magnetic SAF spacer layer having a different composition than the non-magnetic layer.
