摘要：

Superconducting 123 thin films have been produced by RF sputtering with different morphologies. A study is presented of the transport properties (J(c)(T,H)) and the AC diamagnetic screening characteristics for the different samples. Granular films show critical currents two orders of magnitude smaller than textured films at 77 K. This has been explained in terms of the presence of oxygen deficient phases in the intergranular regions.
