Changes in 5d Band Polarization in Rare-Earth Compounds.
X-ray resonant magnetic scattering has been used to examine the magnetic interactions coupling the rare earth and iron sublattices in the antiferromagnetic compound DyFe4Al8. Dramatic differences are observed in the temperature dependencies of the magnetic intensities depending on whether the photon energy is tuned to the Dy L2 or L3 absorption edge. Simulations suggest that thesevariations in intensity are a result of small changes in the orbital occupation and spin polarization within the 5d conduction band.
