Abstract

The effects of oxygen adsorption on the surface magnetization of Gd(0001) have been determined by measuring the polarization of the Gd 4 f core levels and the oxygen induced states with spin-resolved photoemission.Calculations of the partial density of states of O/Gd(0001) using the LMTO-ASA method support the photoemission measurements, which indicate that oxidation occurs at low coverages.The loss of surface magnetic order with oxygen exposure is explained in terms of decreasing indirect coupling.
