The effects of sulphur substitution for oxygen on the structure and properties of nonsuperconducting La2-xSrxCuO4, where x=0.26 and 0.30, have been studied. In La2-xSrxCuO 4-y-Sy, the sulphur-doped samples exhibit superconducting transition at 37-39 K and a larger Meissner effect than undoped samples. It was found that the superconductivity of La2-xSrxCuO4-ySy is apparently determined by the value of x-y and the strontium concentration region in which La2-xSrxCuO4 shows superconductivity shifts to higher strontium concentrations with sulphur doping.
