Abstract
Quantitative analysis of results of measurements of magnetoresistance of Bi2Sr2CaCu2Ox single crystals for magnetic fields 0.2-0.8 T, in the temperature interval 78.5-84 K has been made. For temperatures lower than 81 K the dissipation is predominantly determined by the suppression of the long-range superconducting order, whereas closer to Tc the flux-flow contribution becomes significant. We obtain very good agreement between the experiment and the model in which two dissipation mechanisms are additive.
