Résumé

In this paper we present time-dependent magnetization and high-temperature, low-field critical-current measurements on single crystalline Bi₂Sr₂CaCu₂O₈. A short introduction to thermally activated flux-flow theory (TAFF) is given based on solving a continuity equation for fluxlines with several boundary conditions. A comparison between this theory and our experiments indicates the self consistency of the TAFF model, by relating the temperature dependences of J_c and of the typical relaxation time τ₀ of M(t). Furthermore, values for the pinning potential U are obtained at several temperatures.
