| Popis: | X-ray magnetic circular dichroic measurements at the ${L}_{3,2}$ edges of $\text{Au}$ in $\text{Co}∕\text{Au}$ multilayers are reported. A clear evidence for $\text{Au}$ polarization is provided. The induced magnetic moment of $\text{Au}$ is very small, about one order of magnitude smaller than in Co∕Pt multilayers. The ratio of orbital-to-spin magnetic moment of $\text{Au}$ is found to be ${\ensuremath{\mu}}_{L}∕{\ensuremath{\mu}}_{S}=0.12$. The ferromagnetic response of $\text{Au}$ and its role on the interpretation of the magneto-optic spectra of $\text{Co}∕\text{Au}$ multilayers are discussed with respect to first principle calculations. |
