dc.description.abstractSynchrotron Anomalous X-Ray Scattering near Re (rhenium) edge reveals that the short range structue of Hg0.8Re0.2Ba2Ca2Cu3O8+d compound is not form part of (2a × 2b × 1c) super cell. Moreover, even for a high quality sample (highest Tc and single phase diamagnetic transition), the Synchrotron X-Ray diffraction pattern analyzed by Reitveld refinement confirms there exist two superconductor phases present in the sample produced with optimal oxygen doping content (Hg-1223 and Hg,Re-1223). Extended X-Ray Absorption Fine Structure measurements of the rhenium oxide (VI) sample under external hydrostatic pressure (up to 1.9 GPa)reveal that the ReO6 octahedron spectrum obtained at 1.76 GPa is similar to the ReO6 octahedron inside the (Hg,Re)-1223 structure at ambient pressure. The ReO6 distorted octahedron inside Hg,Re-1223, and the non-existence of (2a × 2b × 1c) super cell can justify the scenario where charge inhomogeneities distribution are present in the outer CuO2 layers.
