Abstract
X-ray magnetic circular dichroism (XMCD) measurements performed at the Rh L -2,L-3 edges and Fd L-3 edge in Fe0.51Rh0.49 and Fe-1.005(Rh0.85Pd0.15)(0.9 95) evidence the instability of the Rh magnetic moment (mu(Rh)) through the ferromagnetic-antiferromagnetic transition and demonstrate the induced nat ure of both mu(Rh), and mu(Pd). In the case of Fe0.51Rh0.49 these experimen ts have also revealed the existence of a ferromagnetic ground state at low temperatures in which mu(Rh)similar to 0.7 mu(B). [S0163-1829(99)11605-9].
