Abstract
A superconductor with nominal composition Hg0.8 Mo0.2 Sr2 Y0.5 Ca0.5 Cu6+d withTc up to 96 K has been isolated and carefully examined by electron diffraction and X-ray energy dispersive spectrum analyses. Its structure can be attributed to space groupP4/mmm and lattice constantsa=3.82 å andc=11.91 å. Inhomogeneous distribution of the cations was observed, which is considered to be the key to the broadening ofdTc in theR-T curve. The effect of humid atmosphere on the stability of the sample has also been investigated.
