Abstract

We have performed photon energy (h nu) dependent hard X-rayphotoemission spectroscopy (HAXPES) for YbCu2Si2, which is a heavy Fermion compound with intermediate Yb valence. We identified that the bulk components in the Si 1s and Yb 3d spectra develop with increasing h nu from 2.5 keV to 6 keV. Moreover, the temperature dependence of the Yb 3d spectra measured at h nu = 8 keV has shown a valence fluctuation behavior. These results suggest that high h nu HAXPES is essential to determine the mean valence of the Yb compounds.
