Description
Summary:The comparison of calculated and experimental parameters of nuclear quadrupole interaction in the sites of crystal lattice of YBa2Cu3O7 and La2–xSrxCuO4 superconducting copper metal oxides has shown that effective charges of all atoms of superconducting ceramic lattices correspond to standard rates of their oxidation, except the atoms of chain and planar oxygen in YBa2Cu3O7 lattice and atoms of planar oxygen in La2–xSrxCuO4 lattice, whose decreased charge is interpreted as a result of hole localization in the corresponding sublattices.
