Josephson junction network as a tool to stimulate intergrain superconducting channels in YBCO films

Recent considerations on the physics of YBa2Cu3O7-delta films made possible explaining their transport properties as flow of supercurrents through lin ks between the granular structure of the film. The present work deals with the analysis of the Josephson junction network as a discrete set of paralle l junctions (1D array) in quasi-static conditions and is aimed to compare t he results of the simulations with the experimental findings, in particular with the plateaulike features in the critical current dependence on the ma gnetic field. Different regimes and vortex phases have been individuated an d discussed.
