We present a detailed study of the influence of the interface properties on the amplitude of the GMR in Fe/Cr superlattices, including changes of the coupling, a synchrotron X-ray diffraction analysis and a theoretical interpretation within the quasi-classical formalism. With increasing amplitude of the interface roughness we observe a reduction of the GMR.
