Abstract

The information of the W- and Ag-induced magnetic moments in Fe/W and NiFe/Ag multilayers was determined separately from the huge 3d magnetic moments with X-ray magnetic circular dichroism. Moreover, their spatial distribution has been extract from X-ray resonant magnetic scattering experiments. It was found that both W and Ag atoms are magnetically polarized and that this polarization extends through all the W and Ag layers, respectively. However, although W is found to be oscillating, the Ag polarization is exponentially decreasing from the interface.
