Abstract

In high temperature superconductors (HTSC), when magnetic relaxation approaches the equilibrium state and the superconductor is applied with current, theE × j relation is calculated by considering both forward and backward hopping of thermally activated flux (where backward hopping means hopping from the barriers with low energy to the ones with high energy). It is pointed out that the InE× Inj curve shows positive curvature. And the results are compared with other models. The discussion on the topic that whether p approaches zero asj → 0 is carried out.
