Abstract
Dependence of the irreversibility field (B-i) on the electric field criteri on (E-C) was measured for a Bi-2223 silver-sheathed tape wire using various measuring methods. It was found that B-i increased monotonically with the electric field criterion. A good agreement was obtained for B-i between exp eriments and the theoretical analysis using the flux creep-flow model. This implies that the resistive property of superconducting wires can be well d escribed by the mechanism of flux creep and flow. The vortex glass-liquid t ransition field (B-g) was also determined from E-J curves which measured in the low and high electric field regions. It was found that B-g also depend s on the ranges of electric field. This is incompatible with the prediction of the vortex glass-liquid transition theory. (C) 2001 Elsevier Science BN .
