Abstract
The effect of the degree of doping with strontium has on the superconducting properties of granular superconductor La2–xSrxCuO4 is considered. It is found that reducing the concentration of strontium under conditions of compositional disorder broadens the superconducting transition above the temperature of intergranular Josephson coupling and raises the temperature of the completion of the global superconducting transition.
