Abstract
The time dependent Ginzburg-Landau equation is used to calculate the anomalous contribution to the conductivity of a dirty superconducting film due to thermodynamic fluctuations above the critical field. Expressions are obtained for the conductivity along the film and also in the surface sheath case above Hc3. It is found that sigma varies as d-3(H2-Hc//2)-1, sigma varies as d-1(H-Hc perpendicular to )-1, sigma varies as (H-Hc3)-1. The conductivity is calculated for a thin film in an inclined field, to get an interpolation formula between the parallel and perpendicular field results.Keywords
