Abstract
Photoelectron spectra of a glassy metal, Ni40Fe40P14B6, have been measured over the excitation-energy range from 30 to 120 eV. The observed overall feature of the valence-band spectrum coincides with that of the reported XPS data, except that a weak broad band extending from 4 to 10 eV is found here. The main 3d-band shows a composite structure; different component-bands have different dependences of ionization cross-sections on the excitation energy. Weak resonant enhancement in the ionization cross-section is found in all the spectral features for excitations around the 3p thresholds of both Fe and Ni. The location of the peak enhanced in the weak-broad-band region upon excitations around the threshold of the Fe 3p-excitation is different from that enhanced upon excitations around the threshold of the Ni 3p-excitation.
