Abstrakt

Measurements of the electrical conductivity, the magnetoconductivity and the Hall effect on thin films of YBaCuO in the regime of thermodynamic fluctuations of the superconducting order parameter are reported. The fluctuation conductivity is in good agreement with the 2-dimensional Aslamazov-Larkin theory. Excess magnetoconductivity and excess Hall effect diverge by higher exponents near the critical temperature indicating a pronounced effect of the magnetic field on the fluctuations.
