Description

The magnetic properties of the disordered alloy systems face-centred-cubic (fcc) CoxRh1-x and fcc FexPd1-x have been investigated by means of the spin-polarized relativistic version of the Korringa-Kohn-Rostoker method of band-structure calculation on the basis of the coherent potential approximation alloy theory. In particular, the spin and spin-orbit-induced orbital magnetic moments have been calculated. In addition, the magnetic circular x-ray dichroism (MCXD) for the x-ray absorption coefficient has been determined. The relationship of the corresponding MCXD spectra and the magnetic moments of the absorber atom is discussed, with most emphasis put on the 4d element, whose magnetism is induced by the alloy partner.
