Abstract
Investigations concerning the magnetic interactions and dispersion effects of oxygen adsorbed on thin cobalt films have been carried out by angle and spin resolving photoelectron spectroscopy. Cobalt evaporated on W(110), showing the surface of a h.c.p. (0001) crystal, served as ferromagnetic substrate. Photoelectron spin analysis allows the distinction between chemisorbed oxygen and cobalt oxide in its different oxidation states (antiferromagnetic CoO and Co 3O 4) at different substrate temperatures. The exchange splittings of the adsorbate derived bands of chemisorbed oxygen are investigated as a function of excitation energy, coverage, temperature, and emission angle. The no-vanishing splittings give evidence for an induced magnetic moment within the adsorbate layer.
