Abstract

The effect of annealing on the superconductivity in the Bi-Pb-Sr-Ca-Cu-O system was investigated. The tailing phenomenon was observed in the R - T curves for all samples annealed at temperatures in the range of 600°C to 825°C though the as-sintered sample showed a superconducting transition above 100 K. This phenomenon was enhanced in the sample annealed at 700°C.
