Abstract

Electrical dissipation on an LPE-grown Bi2212 film was studied using the models of fluctuation magnetoconductivity. The excess conductivity was observed to decrease with increasing field, possibly indicating that pair-breaking is more dominant over Cooper pair formation at the transition region. To further investigate the effect of increasing fields, the behavior of the temperature-dependent coherence length ξ(T) was studied. The ξ(T) was observed to decrease with increasing magnetic field. Any parameter that changes the coherence length so much will cause the dominance of pair-breaking, and macroscopically manifest itself as additional resistance above T_C.
