Abstract
Fluctuation conductivity of epitaxial thin films Bi2Sr2CaCu2O8-delta with and without an applied magnetic field was studied. Obtained results demonstrate the very good agreement with two-dimensional Aslamazov-Larkin theory. In the case of rather weak magnetic field H << H(c2) it was found that all the effect of field reduces to renormalization of critical temperature.
