Abstract
Superconducting 123 thin films have been produced by RF sputtering wit h different morphologies. A study is presented of the transport proper ties (J(c)(T,H)) and the AC diamagnetic screening characteristics for the different samples. Granular films show critical currents two order s of magnitude smaller than textured films at 77 K. This has been expl ained in terms of the presence of oxygen deficient phases in the inter granular regions.
