Summary:
Using a magneto-optic technique we have investigated the magnetic flux propagation into and out of superconducting thin YBa2Cu3O7-b films. After field cooling below Tc, the external magnetic field Bext perpendicular to the film is changed which gives rise to shielding currents in the sample. The current distribution is disturbed momentarily by heating with a focused laser pulse near the sample edge. This triggers a magnetic instability, in which a magnetic flux avalance starts to propagate.
