dc.description.abstract | We report on X-ray photoelectron spectroscopy (XPS) and ab initio electronic structure
investigations of a novel intermetallic material Ce9Ru4Ga5. The compound crystallizes with
a tetragonal unit cell (space group I4mm) that contains three inequivalent Ce atoms sites. The Ce
3d core level XPS spectra indicated an intermediate valence (IV) of selected Ce ions, in line with
the previously reported thermodynamic and spectroscopic data. The ab initio calculations revealed
that Ce1 ions located at 2a Wyckoff positions possess stable trivalent configuration, whereas Ce2
ions that occupy 8d site are intermediate valent. Moreover, for Ce3 ions, located at different 8d
position, a fractional valence was found. The results are discussed in terms of on-site and intersite
hybridization effects. | pl_PL |
