In order to investigate the pinning assist effect of Co<SUB>100-x</SUB>Fe<SUB>x</SUB>-nano-oxide layer (NOL), the MR performance of Co<SUB>100-x</SUB>Fe<SUB>x</SUB>-NOL specular spin-valves with a wide range of Fe contents was studied. Enhancement of both the MR ratio and the exchange bias field was comfirmed by increasing the Fe content in the Co<SUB>100-x</SUB>Fe<SUB>x</SUB>-NOL. This might be due to the interdiffusion of Fe atoms from the nonequilibrium fcc Co<SUB>100-x</SUB>Fe<SUB>x</SUB> layer with high Fe content. Furthermore, a ferrimagnetic component is considered to be formed in Fe-rich Co<SUB>100-x</SUB>Fe<SUB>x</SUB>-NOL, which improves the degradation of the exchange bias field by the ferromagnetic coupling through the NOL.
