Abstract: | We report observation of possible superconducting transitions at 133 K, 117K and 105 K in Bi-Sr-Ca-Cu-O bulk samples which attain zero resistance state above the liquid nitrogen temperature (Tc(0)) = 80K). The transition at 105 K is prominent and shows a significant drop in the sample resistance. X-ray data depict characteristic superconducting peak at 20 = 5–6°. All the specimens show Meissner effect when cooled in liquid nitrogen. |
