The induced magnetic moment of Rh atoms in Coₓ{Rh}_{100{{-}}x}$ alloys (x=77,49) is investigated by x-ray magnetic circular dichroism (XMCD) at the Rh ${M}2,3$ absorption edge. By comparing with the XMCD signal observed in an ${Fe}₇₇Rh₂₃ alloy where the Rh magnetic moment is known, the value of the Rh magnetic moment in Co alloys can be determined (0.6μB for x=77 and 0.1μB for x=51). We find that the Rh moment is about 1/3 the Fe or Co moment for the alloys studied. Analogous measurements of XMCD from a Co₇₁{Ru}₂₉$ alloy show Ru behavior very different from that of Rh, with an induced Ru moment 1/14 the Co moment.
