Abstract
A resistivity anomaly near the superconducting transition temperature is observed in the ab-plane of as-grown Bi2Sr2CaCu2O8 (Bi-2 2 1 2) sin gle crystals. The resistivity at the peak is much larger than the norm al state resistivity around 100 K. The peak vanished gradually with in creasing the applied magnetic field. I-V curves of the Bi-2 2 1 2 samp les also exhibit a peak close to the transition steps, vanishing gradu ally with increasing intrinsic granularity of high-T-c superconductors .
