SXF Si L-emission spectra for an FeSi2 reference sample and for the two polycrystalline Fe/Si multilayers whose magnetization curves are shown in Figure 1. The incident photon energy was 132 eV. The data labelled ``Uncoupled ML'' is from the (Fe30Å/Si20Å)x50 multilayer grown on glass. The data labelled ``AF-coupled ML'' is from the antiferromagnetically coupled (Fe30Å/Si14Å)x50 multilayer grown on glass.
