Abstract

Superconducting bulk La_2-xSr_xCuO₄ with doping concentration x = 0, 0.14, 0.16, 0.18 and 0.20 were synthesized via solid state reaction technique. X-ray diffraction data, SEM images and AC magnetic susceptibility were used to study the grain morphology, crystal properties and superconductivity of the samples. Results indicate effective Sr doping on the samples. The critical temperature of the samples is lower than the maximum T_c of 38K due to annealing in ambient atmosphere
