Abstract

We describe x-ray and UV photoemission measurements of the valence bands and core level shifts in Ag₃Mg and in AgMg (CsCl structure), and the results are compared with pure Ag. As far as we are aware, this is the first report of such an investigation on Ag₃Mg alloys. We find that the valence bandwidths of alloys are narrower than that of pure Ag. As part of the study, we calculated the density of states and band structure of Ag₃Mg (L12 structure) and AgMg (CsC1 structure) using the SCF-LMTO-ASA method. The calculations are in general agreement with the measurements.
