Abstract

A study on optimizing the giant magnetoresistance of NiFe/Cu/Co pseudo spin-valves was presented. The puseodo spin-valves were prepared by dc magnetron sputtering and a base pressure of 1×10^-7 mbar was achieved by turbomolecular pumps. Magneto-optic kerr-effect measurements revealed different coercive fields and independent switching of the Co and NiFe layers. The reduced coercive field and low GMR ratio indicated that the clustered grain possesed weaker magnetic pinning and increased spin-independent scattering.
