Abstract

We have investigated the magnetic flux motion in a high quality YBCO disk induced by a pulsed magnetic field. The effect of static bias fields was also studied in the temperature range of 30-95 K. The flux flow resistivity ρ_f increased with increasing the pulsed magnetic field approximately according to the Bardeen-Stephen model, that is ρ_f/ρ_n ≈ B/B_c2. The viscosity coefficient η decreased with increasing temperature and static bias field.
