Pb2Sr2Ceo.sCao.sCu30 s and Pb2Sr2Lnl\_xCaxCu308 with Ln =Pr, Tb and x= 0.0 and 0.5 have been studied by rare-earth L ILm edge XANES spectroscopy. The spectra of Pb 2 Sr2Ceo.sCao.sCu 308 show that Ca doping of Pb 2 Sr2CeCu 308 causes a partial oxidation of Ce. Analysis within the framework of the And
The electronic structures of the -Ln 2 S 3 (Ln β«Ψβ¬ La, Ce, Pr, and Nd) light rare earth sulfides are studied by means of the ab initio self consistent LMTO-ASA method in the tight-binding representation. Results show that the valence and the conduction bands are mainly S 3p and Ln 5d in character, r
