Critical current of Bi2223 superconducting tape and extended exponential model

We have measured J c( B, T) mainly at 4.2 and 77 K under perpendicular external fields and parallel ones. The results make it possible to elucidate the critical state model theoretically and experimentally. In the present work, an attempt has been made to elucidate the critical state model of high-...

Description
Summary:	We have measured J c( B, T) mainly at 4.2 and 77 K under perpendicular external fields and parallel ones. The results make it possible to elucidate the critical state model theoretically and experimentally. In the present work, an attempt has been made to elucidate the critical state model of high- T c superconductors theoretically according the measured J c( B, T) characteristics. Possible explanations of hysteretic J c versus H e characteristic were presented and discussed.
