Specific intermediate-valence state of insulating 4f compounds detected by L3 x-ray absorption.

TL;DR: It is shown that the many-body final states arise from the characteristic properties of these materials: the presence of localized 4f level above the oxygen 2p band separated by a gap and the mixing of 4f localized states with ligand valence orbitals such that the hybridization energy V is of the same order of magnitude as the energy separation \ensuremath{\Delta}E.
Journal ArticleDOI

Multiple-scattering regime and higher-order correlations in x-ray-absorption spectra of liquid solutions

TL;DR: In this paper, the energy extent of the type-II multiple-scattering (MS) regime was determined by making a comparison between the Mn K-edge absorption of (${\mathrm{MnO}}_{4}$${) and [Mn${H}}_{2}$O${)}_{6}$ ] 2+}$ complexes in aqueous solution.
Journal ArticleDOI

L2,3 XANES of the High Tc Superconductor YBa2Cu3O~7 with Variable Oxygen Content

TL;DR: In this paper, the copper L2,3 soft x-ray absorption spectra of the single phase high temperature superconductor YBa2Cu3O≈7 have been measured by using synchrotron radiation at LURE.
Journal ArticleDOI

Symmetry of the 3d9 ligand hole induced by doping in YBa2Cu

TL;DR: In this article, the symmetry of the orbital of the electronic holes induced by doping was determined for a single crystal of YBa/sub 2/Cu/sub 3/O/sub 7-//sub delta/ (0.
