Sažetak
In the mixed state of superconductors (H-c1 much less than H much less than H-c2) the penetration of microwaves is governed by both, complex conductivity sigma(T) and driven oscillation of vortices. In this paper, we show that an effective microwave conductivity can be derived and used to fit the field dependences of the surface resistance R(s). The fit parameter is the upper critical field. Measurements on single crystals YBa2Cu3O7-delta were made in magnetic fields (H parallel to c) up to 2.25 T, and in the temperature range from 70-100 K. The critical temperature for mean field superconductivity appears to be 89.3 K, while the apparent onset in the curve of R(s)(T) appears at about 92 K. The magnetic dependences of R(s) clearly demonstrate that one can separate the regions of mean field superconductivity from the region of fluctuations. [References: 19]
