Abstract

It is very important to know electric field (E) vs. current density (J) characteristics on temperature (T) and magnetic field (B) in practical wire for High T c superconductor (HTS) application. We obtained the scaling characteristics of E-J in Bi-2223/Ag wires by parameters of Weibull function expressing the J c distribution, or J cm and J 0, instead of the scaling by using conventional J c value for a specific electric field criterion. Scaling characteristics of pinning force in wide range of T and B for B-directions of parallel and perpendicular to sample surfaces are also shown.
