Description

By using a unified empirical procedure, the intrinsic paraconductivity in the ab plane, Δσi, is extracted from different available data for resistivity rounding in single-crystal and granular YBa2Cu3O7-δ samples, and from data in Bi1.5Pb0.5Sr2Ca2Cu3Oy granular samples. These results strongly suggest that both high-temperature superconductor systems will have relatively strong pair-breaking effects, and that Δσi may be explained by direct superconducting order-parameter-fluctuation effects alone
