The effect of inserted Cu was studied on current-perpendicular-to-plane-giant magnetoresistance of Fe50Co50 spin valves. The investigation of structural state of the inserted Cu was done by extended x-ray absorption structure (EXAFS) spectra to clarify its role in specific resistance behavior. It was found that solid solute Cu participates in the specific resistance increase in Fe50Co50 spin valves.
