摘要：
Spin-resolved x-ray photoelectron spectroscopy and high-resolution x-ray photoelectron spectroscopy studies of the valence electronic structure of ferromagnetic Fe, Co, Co66Fe4Ni1B14Si15, and Ni are reported, and compared with theoretical densities of states. Agreement between theory and experiment is very good for ferromagnetic Fe and Co66Fe4Ni1B14Si15. For metallic Co, experiment agrees poorly with theory incorporating a 1.5 eV exchange splitting, suggesting a reduced (1.2 eV) exchange splitting attributable to valence electron correlation in Co metal. Ferromagnetic Ni shows poor agreement between experiment and theory, particularly in the up arrow(-)spin channel. (C) 1998 American Institute of Physics.
