Abstract
We have investigated the magnetic flux motion in a high quality YBCO disk i nduced by a pulsed magnetic field. The effect of static bias fields was als o studied in the temperature range of 30-95 K. The flux flow resistivity rh o (f) increased with increasing the pulsed magnetic field approximately acc ording to the Bardeen-Stephen model, that is rho (f)/rho (n) approximate to B/B-c2. The viscosity coefficient eta decreased with increasing temperatur e and static bias field. (C) 2001 Published by Elsevier Science B.V.
