Abstract	The layer-averaged magnetic moments of Co and Rh have been measured in sputter deposited Co/Rh ~001! multilayer thin films using the x-ray magnetic circular dichroism. The Rh moments were measured at both the L and M absorption edges, where we find that the Rh moment decreases as a function of increasing Rh layer thickness ( t Rh). The decline of the layer-averaged Rh moment is well described in terms of a simple dilution, implying that the Rh moment is confined to the interfacial region. We find that the Co moment remains largely unaffected, maintaining a bulklike value of 1.7m B in the region preceding the first antiferromagnetic coupling peak where t Rh ranges from 0 to 4 A. We also find, via application of the dichroism sum rules, that the ratio ^Lz&/^Sz& for Co increases ’10% for this same region. Finally, we contrast the magnetic behavior of the Co/Rh ~001! and Fe/Rh ~001! multilayer systems. @S0163-1829~98!07641-3#
