Abstract
Current-voltage characteristics of Bi2Sr2Ca2Cu3O10 tapes and bulk samples with preferentially oriented crystallites have been measured in zero applied magnetic field and for temperatures close to the mean-field critical-temperature,T c0. It was shown that the power-law dependence,V=AI a, valid for two-dimensional systems, does not correctly describe the data, which clearly indicate the existence of a finite critical-current density,J c. The experimentalI-V curves are fitted quite well with the model which attributes the finite critical-current density to the coupling between the CuO2 double layers. It was found thatJ c vanishes at a temperature value belowT c0. This behavior can result from the occurrence of vortex fluctuation-induced layer decoupling and/or from the contribution of entropy to the vortex unbinding process.
