Abstract
The critical current density J.sub.c of a superconductive oxide film can be tailored, without substantial change in the critical temperature T.sub.c (R.dbd.0), by introduction of radiation damage into the superconductor. Exemplarily, this is done by exposure to energetic (e.g., 1 MeV) ions. The ability to tailor J.sub.c permits optimization of SQUIDS and other thin film devices, and makes it possible to produce superconductive interconnects that comprise "fuses" or current limiters.
