Time resolved nanosecond vortex dynamics in high Tc superconducting films

Flux dynamics in a high Tc superconducting thin film is investigated in the ns time scale. The initial metastable state is determined by applying a pulsed magnetic field to a sample previous cooled below the irreversibility line. Selective local heating of the film with a pulsed laser spot lowers th...
