ELECTRONIC-STRUCTURE OF GD(AL1-XCOX)2 INTERMETALLIC COMPOUNDS

The electronic structure of Gd(Al1-xCo(x))2 compounds for Co concentra tions x = 0.0, 0.05, 0.1, 1.0 was investigated by X-ray photoelectron spectroscopy. An energetic shift of the Gd 4f majority spin peak on do ping with Co is not detectable. The shape of the occupied Co 3d valenc e band near the Fermi level in pure GdCo2 is in good agreement with ca lculations of the density of states for paramagnetic YbCo2 from the li terature. Slight discrepancies between experiment and theory can be at tributed to the intrinsic magnetism of the Co sublattice in GdCo2.
