Abstract
We have studied a method to evaluate electric field (E) vs. current density (J) characteristics of high temperature superconductors as a basis for their power device application. The E-J characteristics of Bi-2223 wires were measured in a wide range of magnetic field and temperature. Those characteristics are discussed by the theory of critical-current-density distribution and by the scaling law of the pinning force.
