Abstract
We reanalyze theoretically the fluctuation-induced electric conductivity in high-Tc superconductors, since an early theory proposed by Aronov et al. contains an error. When this error is corrected, we find that the dirty-limit theory cannot describe the magnetoconductance data obtained in a monocrystal of Y-Ba-Cu-O by Matsuda et al. The clean-limit theory, on the other hand, describes the data somewhat better. Finally, inclusion of the nonlocal effect in the clean-limit theory removes most of the discrepancy between theory and experiment.
