The structure and cationic composition of oxides of the Ba-Cu-O system with cubic BaCuO2 and tetragonal BaCu2O2 structure and YBa2Cu3O6 + δ oxide of the Y-Ba-Cu-O system are studied. The oxides are found to be nonstoichiometric in cationic composition when the composition differs noticeably from the corresponding formula relation with conservation of the crystalline structure’s type.
