SYNTHESIS AT AMBIENT PRESSURE AND SUPERCONDUCTIVITY OF Hg-DOPED TI-BASED DOUBLE [(T1, Hg)-O]-LAYERED CDPHATES

The Hg-doped T1-based 2201 and 2212 phase layered cuprates have been successfully syn-thesized at ambient pressure and identified by X-ray powder diffraction and electron diffraction analysis. Compared with pure T1-based 2212 phase compound, there are indications that the corresponding Hg-doped T1-based compound (T11.8Hg0.2)Ba2CaCu2Oz exhibits much higher Tc (> 132K).
