Abstract

Hgl201 superconductors have been synthesized from Ba-Cu-O precursors in a two zone assembly. Critical temperatures of 92 K as prepared and 95 K after oxygen annealing resulted. The Hg1201 phase forms at mercury pressures above 6 bar (800C) and at temperatures between 750°C and 850°C. The effect of dopants on melting and annealing temperatures of the precursor materials has also been studied. After Li doping of, up to 20 melting %, peaks shift to lower temperatures and broaden significantly.
