Abstract
Microwave magnetoresistance was measured in a YBa2Cu3O7−δ single crystal. The analysis of the experimental curves shows that one can distinguish between the contributions from mean-field superconductivity and fluctuations. The behavior of the former yields a mean field Tc, while the latter is used to analyze the scaling properties of the fluctuation conductivity with a predetermined Tc.
