Abstract
Samples of Bi2223 superconductors were prepared with traditional PIT process. The critical current was measured with the four-point method. The criterion of 1μV/cm was used to define its critical curent. All measurements were done with the samples immersed in liquid helium. Different equations are introduced to fit the experimental results under low and high applied mag-netic field. Several factors are also considered to investigate the hysterestic behavior.
