Pulsed-laser heating of current-biased percolative YBa2Cu3O7-delta films can be used to generate and release self-field-induced vortices. A laser pulse yields a voltage signal due to penetration of bias-current-induced magnetic flux in absence of an external magnetic field. Upon recooling, strongly pinned vortices remain in the film. These remanent vortices have been detected after disconnecting the bias source in the currentless film. Applying a subsequent second laser pulse again yields a signal voltage but of opposite sign due to magnetic flux redistribution. This phenomenon could be applied as write-read memory.
