Zusammenfassung

We have investigated the short time dynamics in the magnetic flux distribution of thin YBa2Cu3O7-x films by means of time resolved magnetooptics. Local heating of the superconductor with a focussed laser pulse in a region with high shielding currents leads to an instability in the magnetic flux distribution. A pump probe technique allowed to visualize changes in the flux distribultion on a nanosecond time sale. The instability develops in two steps giving rise to additional flux penetration and to a branching of the flux front into the superconductor.
