Electronic Structure of Pd_42.5Ni_7.5Cu₃₀P₂₀ Metallic Glass

摘要

In-house photoemission and inverse-photoemission spectra (PES and IPES) were measured on Pd_42.5Ni_7.5Cu₃₀P₂₀ and Pd₄₀Ni₄₀P₂₀ bulk metallic glasses together with incident photon-energy dependent PES spectra using synchrotron radiation. Minima are observed at slightly higher energy than the Fermi level. Pd 4d, Ni 3d and Cu 3d partial density of states were estimated from the PES and soft X-ray emission spectra, and the feature of the electronic structure in these glasses were discussed in detail in connection to the excellent glass-forming ability.
