dc.description.abstract | We present a combined experimental and theoretical study of the electronic structure for the
heavy-fermion antiferromagnet Ce5Rh4Sn10 based on X-ray photoemission spectroscopy (XPS) data and
ab initio band structure calculations. The Ce core-level XPS spectra point to a stable trivalent configuration
of Ce atoms in Ce5Rh4Sn10, consistently with both the magnetic susceptibility data and the results of
computational structure optimization. The band structure calculations confirm a magnetic ground state
with significant magnetic moments only at the Ce atoms. The qualitatively correct description of Ce3+ in
Ce5Rh4Sn10 has been achieved using the LSDA+U approach for the Ce 4f states. The comparison of the
theoretical results with experimental XPS valence band spectrum supports their validity. The calculated
partial densities of states suggest that there is a variation in binding energy of the occupied 4f states
between Ce atoms in nonequivalent crystallographic positions, which is related to the hybridization with
Sn states. Finally, the band structure and charge density maps point to the formation of zig-zag chains of
the strongly bounded Sn(2), Sn(3) and Rh atoms along the tetragonal axis, whereas Sn(1) shows nearly
dispersionless 5s bands. | pl_PL |
