We propose a comparative and critical assessment of multiple scattering expansions. The so-called multiple scattering series expansion is much used in the description of spectroscopies at higher energies. However, it is plagued with convergence probl

We analyse the problem of the electronic correlations in V2O3, focusing on its low-temperature antiferromagnetic phase, in the light of recent experimental findings. In fact, the implications of the vanadium K-edge linear dichroism data demand furthe

As 3d spin-orbit branching ratios have been measured as functions of azimuthal angle for the 1 monolayer As Si (111) -(1 × 1) and As Si (001) -(2 × 1) systems using angle resolved photoemission. At a photon energy of hv = 72 eV, the branching ratio

International audience; We have performed extended x-ray absorption fine-structure (EXAFS) spectroscopy on a 2.8% Cr-doped V2O3 sample, with the aim of studying its structural evolution in a wide temperature range across the paramagnetic-antiferromag

We report on experimental oxygen K-edge x-ray absorption near edge structure (XANES) spectra of the LaFe1 - xGaxO3 and LaMn1 - xGaxO3 series. Transition metal substitution by the 3d full shell Ga atom is mainly reflected in a systematic decrease of t
