Abstract

Field- and temperature-dependent microwave measurements have been carried out on (formula presented) thin film grown on (formula presented) substrate. The analysis reveals the mean-field coherence length (formula presented) in the mixed state and a temperature-independent anisotropy ratio (formula presented) At the superconducting transition, the scaling of the fluctuation conductivity yields the Ginzburg-Landau coherence length with a different anisotropy ratio (formula presented) also temperature independent.
