| dc.description | The valence band electronic structure of the intermetallic compounds and has been investigated by means of synchrotron radiation ultraviolet photoemission. The spectra exhibit band structure extending to approximately 8 eV below the Fermi level for each alloy. Utilizing the Cooper minimum in the Pt 5d photoionization cross-section, the partial densities of states have been empirically determined. The results indicate that the d bands of the constituent metals completely overlap. The V 3d states contribute most strongly to the valence band immediately below the Fermi level. In contrast, the highest occupied density of states for the Mn 3d band lies approximately 2.6 eV below the Fermi level. For , 3p to 3d resonant photoemission confirms the results obtained at the Pt 5d Cooper minimum. However, no clear evidence for a corresponding V 3p to 3d resonance was observed in . This may indicate that the V d states in are significantly less localized than the Mn d states in . The empirical results for each alloy have been compared with theoretical calculations from the literature and provide good agreement in each case. |
