Abstract

By simultaneous measurements of sample resistance and of X-ray resonant scattering, we tried to establish a direct correlation between magnetoresistance (MR) and antiferromagnetic (AF) order in a Co/Cu metallic multilayer. Field-dependent scattered intensity has been measured in a geometrical configuration corresponding to the Bragg peak coming from the AF coupling, at a photon energy close to the CoL3absorption edge(hν = 776.5eV). The comparison between measurements of the scattered intensity and of the resistance clearly shows a direct correlation between AF order and MR.
