Abstract The critical current density Jc of a superconductive oxide film can be tailored, without substantial change in the critical temperature Tc(R=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 Jc permits optimization of SQUIDS and other thin film devices and makes it possible to, produce superconductive interconnects that comprise "fuses" or current limiters.
