Description

We present a comparative study of the electronic structure of the superconducting skutterudite SrPt4Ge12 by means of soft X-ray photoelectron spectroscopy and full potential band structure calculations. Excellent agreement between the measured and the calculated valence spectra is observed, confirming the picture of rather localized, low lying Pt 5d states compared to Pt metal. This implicates that the states at the Fermi level stem predominantly from Ge 4p electrons. An analysis of the chemical bonding in SrPt4Ge12 based on the electron localizability indicator is given.
