Abstract

Resistance measurements were performed on Bi2Sr2CaCu2O8+δ films with different applied currents. It was found that with increasing applied current, the transition shifts to lower temperature while a tail develops, characterized by a broadening with the presence of defects in a sample. The broadening of the tail regime manifests the dissipative hopping motion of induced vortices from one pinning site to another. From a critical current plot, the critical temperatures of the samples were determined, independent of the shifting effects of increasing applied current.
