Abstract
The valence bands and core levels of a wide variety of metallic glasses (FeZr, CoZr, NiZr, CuZr, PdZr, PtZr, CuTi, NiNb and NiTa) have been studied by UPS and XPS. The valence band spectra are characterized by varying d-band splitting and binding energy shift. Within a given series the d-band splitting is increased with increasing number of groups between the two constituents in the periodic table. The correlation between this electronic structure and glass forming ability and alloy heats of formation is discussed.
