Abstract
Ternary vintl phases MgMv (M ≡ Au, Pt, Pd; v ≡ Sn, Sb) have been studied by v-ray photoelectron and Auger spectroscopy. From an appropriate combination of binding energy and Auger kinetic energy shifts it is possible to derive an evperimental estimate for the final state relavation contributions. Inclusion of the relavation contributions and of changes in the work function allows the determination of the atomic charges for all three constituents. The phases turn out to be much less ionic than predicted by a formal application of the evtended vintl concept. This result is in accordance with earlier suggestions derived from reflection spectroscopy.
