X-ray spectra and electronic structure of some high-temperature superconductors and attendant metal oxides

By Ereshchenko Anatoly Anatolievich


The investigation is concerned with Y_1_-_xR_xBa_2Cu_3O_7_-_ delta (R-Pr, Er), La_2_-_xSr_xCuO_4_-_ delta , Tl_2Sr_2Ca_2Cu_3O_1_0, Bi_2Sr_2Ca_2Cu_3O_10 high-temperature superconductors. The aim of the work is to study reqularities of forming a valence band and character of interaction of elements and reveal its connection with T_c in doped metal ceramics. The new data on partial distributions of density of states of the valence band of the high-temperature superconductors, atoms charge states has been obtained, in some cases the interaction of features of the electronic structure with the physical properties of objects has been revealed. The technique of comprative analysis of the charge states of 3d-metals has been developedAvailable from VNTIC / VNTIC - Scientific & Technical Information Centre of RussiaSIGLERURussian Federatio
