Abstract
Field dependence of the microwave surface resistance in YBa2Cu3O7−δ single crystal is analysed in terms of the mixed state and superconducting fluctuations. Careful fitting of the appropriate parts of the magnetoresistance curves yields the upper critical field, and mean field Tc. The microwave fluctuations conductivity is found to scale as predicted for a three dimensional (3D) superconductor.
