Abstract :
X-ray absorption spectrum of the Sm L3 edge have been measured in the intermediate valence Sm1−xYxS for two dopant concentrations x = 0.33 and 0.45. From the analysis of near-edge structure using the method that takes into consideration multiple scattering effects we managed to specify Sm valence value more precisely in wide temperature interval. Sm local crystalline structure was analyzed by EXAFS-spectroscopy; Sm-S coordination sphere parameters were obtained.
