Abstract

The magnetoresistance (MR) properties of a basic Ta/NiFe/IrMn/CoFe/Ru/CoFe/Cu/CoFe/Cu/Ta synthetic spin valves (SV) system was systematically studied by using O₂-soaked layers in five different positions. It was found that the crystal structure does not significantly change at an optimized O₂ soaking dose (OSD) where the MR ratio was maximal. Results showed that increasing the spin-dependent coefficient and reducing the diffusion scattering coefficient either at the interface or within the ferromagnetic (FM) layers could enhance MR ratio.
