The giant magnetoresistance (GMR) of a Fe/Cr multilayer decreased on annealing and was accompanied by a reduction in anti-ferromagnetic (AF) coupling. The underlying structural changes were studied using grazing incidence X-ray scattering. Specular and diffuse measurements were used to characterize the interface roughness which has been found to be mostly uncorrelated and increased upon annealing.
