Abstract
Electronic structure of La2−x Ba x CuO4 superconductors has been studied. Model systems La10CuO −1222 , La10cuO +414 and LagBaCuO +314 with various Ba positions have been investigated using the quasirelativistic INDO molecular orbital method. The oxidation state of copper atoms corresponds to Cu(II). The influence of Ba/La substitution on copper atoms is much lower than on their oxygen ligands sphere.
