Abstract

We have prepared the sulfide analogues of the new warm (≈ 90 K) superconducting oxides (M1M′2Cu3X8-δ, M = Y, Eu, Gd, M′=Ba, X=S and δ= 0 to 1.5). These are referred to in the literature by the stiochiometry e.g., (1, 2, 3, 7.1) is one of the superconducting phases reported in the literature. The purpose of this work is to find out if the sulfide analogues of the above oxides can be prepared by high temperature reactions in a sulphur atmosphere, the composition of the metallic (superconducting?) phases if present and the structure of the unit cell.
