摘要：

Magnetic-field-dependent fluctuation conductivity in the a-b plane of single-crystal YBa2Cu3Oy is evaluated using recent theories for layered superconductors considering both Aslamozov-Larkin and Maki-Thompson terms. The normal resistivity, without fluctuation conductivity effects, is also estimated in the temperature region above Tc using the parameters obtained from the analysis of the field-dependent fluctuation conductivity. The result is substantially different from previously estimated values that are linearly extrapolated from high-temperature data. © 1990 The American Physical Society.
