Abstract
Tl-1223 thick films were grown on single crystalline LaAlO3 substrates by a screen printing method and doped with different amounts of 235 U. The critical current density was measured by dc transport measurements in fields up to 6 T and at temperatures between 85 K and 40 K. Furthermore, the angular dependence of the critical current density and of the irreversibility lines was studied. Excellent texture and very high critical current densities with a weak field dependence were found in the as grown samples. Substantial enhancements of the critical current density and enhanced irreversibility lines are observed after thermal and fast neutron irradiation. The weak field dependence of Jc is further reduced. The results are compared with YBaCuO coated conductors and BiSCCO-2223 tapes.
