Abstract

The Giant magnetoresistance behavior of Co/CuMn/Co sandwich structures has been investigated, combined with the surface magneto-optical Kerr effect (SMOKE) method in air. Very low saturation/switching field was achieved by diluting Mn atoms into the Cu metal, but GMR value has no much change, which may imply a way to get high sensitive GMR material. The SMOKE measurements showed steps in Kerr loop, indicating the antiparallel alignment of magnetizations between two neighbored Co layers due to their different switching fields.
