CRYSTAL-STRUCTURE OF THE DOUBLE-HG-LAYER COPPER-OXIDE SUPERCONDUCTOR (HG,PR)(2)BA-2(Y,CA)CU2O8-DELTA AS A FUNCTION OF DOPING

Abstract:

The crystal structure of the newly discovered double-Hg-layer copper oxide superconductor (Hg, Pr)2Ba2(Y, Ca)Cu2O8-δ was studied as a function of chemical doping using neutron and electron diffraction and high-resolution transmission electron microscopy (HREM). Rietveld refinements of the structural parameters from neutron powder diffraction data indicate that the oxygen site O3 on the mercury plane is highly defective, being both partially occupied and displaced from the high-symmetry positi...
