Journal ArticleDOI
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
Maurizio Benfatto,Calogero R. Natoli,Antonio Bianconi,J. Garcia,Augusto Marcelli,M. Fanfoni,Ivan Davoli +6 more
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
Antonio Bianconi,A. Congiu Castellano,M. De Santis,Petra Rudolf,P. Lagarde,A.M. Flank,Augusto Marcelli +6 more
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.
