AbstractAbstract

[en] We grew single crystals of La_2-xSr_xCuO₄ with Sr-concentration gradient along the crystal growth. Doping dependence of the superconducting transition temperature T_c was determined by magnetic susceptibility measurement at different positions of the crystal. The results revealed a dramatic degradation of superconductivity at around x∼0.12 more clearly compared to the previously determined phase diagram using powder samples or single crystals with uniform Sr-concentration
