Abstract

Pining characteristics due to the precipitates of the “3321”(Sr2.5Bi0.5Pb3Ca2CuO2) phase have been studied in the Bi-2223 phase in the Bi-Pb-Sr-Ca-Cu-O system by mainly XRD and magnetic measurements. The precipitation of the “3321”, phase was controlled by changing annealing temperature and annealing time in air. On annealing at 750°C for lOmin and lh, the larger hysteresis loops in M-H curves were observed in comparison with the initial one before annealing. However, the hysteresis loops became smaller with increasing precipitation of the “3321”, phase. Furthermore, the 2223 phase annealed at 400°C and 500°C, in which no precipitation of the “3321” phase was observed, exhibits larger hysteresis loops.
