Moreover, even for a high quality sample (highest Tc and single phase diamagnetic transition), the synchrotron X-ray diffraction pattern analyzed by Rietveld refinement confirms there exist two superconducting phases present in the sample produced with optimal oxygen doping content (Hg-1223 and Hg,Re-1223). The non-existence of (2a × 2b × 1c) super cell can justify the scenario where charge inhomogeneities distribution are present in the outer CuO2 layers.1182-1183openAccessbarium compoundscalcium compoundscopper compoundscopper oxidesdistributionlattice parameterslayersmercury compoundsoxygen compoundsrhenium compoundsscatteringsegregationsuperconductorssynchrotron radiationtransition temperaturex-ray diffractionArtigo de periódico460-46210.1016/j.physc.2007.03.420https://orcid.org/0000-0001-7707-7821https://orcid.org/0000-0002-8304-9939
