Abstract
We studied the metal and O -derived electronic states of Ru, Ir, , and by photoemission spectroscopy with synchrotron radiation. Our data are in qualitative agreement with the Ru and Ir density-of-states curves calculated by Mattheis, which consist of one -electron peak and three other major peaks with prevailing O character. The quantitative agreement is reasonably good for Ru, while discrepancies exist for the lower-energy states of Ir. Revelation of these discrepancies, not evident from previous photoemission studies, was made possible by the investigation of mixed Ru-Ir crystals.
