Abstract

Polycrystalline Fe/Cr multilayer films were grown by sputter deposition. The as-grown films showed a mixture of ferromagnetic (FM) and antiferromagnetic (AF) coupling, with an unusually small magnetoresistance (MR) given the degree of AF coupling observed. Annealing for 1 h at 300°C increases the AF component, and the MR increases accordingly. Annealing for one more hour, however, decreases the AF component again with a reduction of MR. Changes in microstructure observed on annealing suggest that interface roughness and pin holes in the film are key factors in determining the magnitude of the GMR effect.
