Abstract

In this paper we report the results of a synchrotron X-ray diffraction study of epitaxial, [111]-oriented Co/Pt multilayers which demonstrates the existence of interfacial mixing and extensive chemical ordering in the multilayers. We also report new magnetic data for epitaxial Co/Pt multilayers, grown along the 3 major axes: [111], [110] and [001], which demonstrate that both the interface anisotropy (KS) and volume anisotropy (KV) constants depend on the growth axis of the multilayer. This study suggests that chemical interdiffusion and chemical ordering within the interfaces, as well as strain, should be incorporated into a realistic model for the magnetic anisotropy.
