摘要：
A spin valve magnetoresistance element has an even number of free layer structures having ferromagnetic or antiferromagentic coupling with respecto to associated pinning layers via non-magnetic spacers. It may have a configuration in which one half of the free layer structures has an antiferromagnetic coupling and the other half has a ferromagnetic coupling with respect to associated pinned layers. The different couplings are the result of an even number different spacer layers having respective different thicknesses.
