Abstract

We present measurements of the microwave resistivity at 48 GHz in YBa[sub 2]Cu[sub 3] O[sub 7]-δ film, as a function of the temperature and the magnetic field. The magneto-dissipation from 60 K up to a few kelvins below T[sub c] finds a quantitative description in terms of free flux flow. Approaching T[sub c], the data are not consistent with a dissipative mechanism based solely on flux dynamic. Fluxon viscosity is measured as a function of the temperature, and the in-plane coherence length is estimated. The analysis of the zero-field transition at 48 GHz in terms of anisotropic renormalized fluctuations yields identical estimate. [ABSTRACT FROM AUTHOR]
