Abstract

The effects of sulphur substitution for oxygen on the structure and properties of nonsuperconducting La_2-xSr_xCuO₄, where x=0.26 and 0.30, have been studied. In La_2-xSr_xCuO _4-y-S_y, 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 La_2-xSr_xCuO_4-yS_y is apparently determined by the value of x-y and the strontium concentration region in which La_2-xSr_xCuO₄ shows superconductivity shifts to higher strontium concentrations with sulphur doping.
