The isostructural α-γ phase transition in cerium is analyzed using density-functional theory
with different exchange-correlation functionals, in particular the PBE0 hybrid functional and …

The present review summarizes important aspects of the crystal chemistry of ytterbium-
based intermetallic compounds along with a selection of their outstanding physical …

The Structure of Rare-Earth Metal Surfaces introduces the concepts of surface
crystallography and surface-structure determination, outlines the principles of the most …

We exploited complementary synchrotron radiation spectroscopies to study the Yb 4 f
electronic configuration in three representative intermediate-valence materials: Yb Al 3, Yb …

We present temperature-dependent photoemission (PES) measurements on single-
crystalline YbInCu 4, a stoichiometric material that shows an isostructural first-order valence …

In order to elucidate the temperature‐dependent occupancy number of Ce 4 f electrons and
valence state of Ce ions in cerium mononitride (CeN), we perform an ab initio calculation by …

In order to investigate the structure-dependent correlation strength and occupation number
of 4f electrons in cerium monoarsenide (CeAs) with the NaCl-type (B1-type) and CsCl-type …

The electronic structure of 26 Yb compounds is calculated with the ab initio self-interaction-
corrected local-spin-density approximation. In this approach f electrons can be described as …

Heavy-fermion compounds YbIr 2 Si 2 and YbRh 2 Si 2 were studied by means of angle-
resolved photoemission (PE). The splittings and dispersions of the 4 f 13 bulk and surface …
