Abstract
The dynamical behavior of magnetic flux in superconducting Tl-Ba-Ca-Cu -O films has been studied using the Nernst effect. Large temperature g radients of approximately 10(5) K/cm and, correspondingly, large therm al forces on flux lines were obtained by pulsed laser heating of films . Due to the large thermal driving forces it was possible to observe, at temperatures well below T(c), the transition from thermally assiste d flux flow to flux creep and viscous flux flow.
