Abstract
Simple(CuO2, CuO) and complex superconducting (YBa2Cu3O7-x, La2-xSrxCu O4) copper oxides have been investigated by Cu-61(Ni-61) emission Moss bauer spectroscopy. A linear relationship between the quadrupole coupl ing constant for Ni-61 and the calculated lattice electric held gradie nts is established, and the contribution of the Ni2+ valence electrons to the coupling constant is determined. Magnetic fields are observed at Ni-61 nuclei in those cases when the copper sublattice shows magnet ic ordering.
