Electronic structure of T5T9 metallic glasses (T5=Nb,Ta; T9=Rh,Ir) studied by photoelectron spectroscopy

Photoelectron spectroscopy of glassy Nb55Rh45, Nb55Ir45, Ta55Rh45, and Ta55Ir45 alloys reveal a common d band of the two alloy constituents with a large shift of the T9 metal d states to higher, and a shift of the T5 metal d states to lower binding energies relative to the corresponding pure metal. The charge transferred from the T5 to T9 metal on alloying is quite small and results in a small (positive and negative) binding-energy shift of the core electrons of the T9 metal. © 1982 The American Physical Society.
