Abstract
The high-T-c superconducting system YBa2Cu3Odelta:Li (123) was investi gated by microwave absorption. The effect of neutron irradiation on th e 123 phase as well as the dependence of the resulting modification bo th on the neutron fluence and on the doping behavior with Li are discu ssed. The results show a significant improvement of the superconductin g characteristics: critical temperature, phase homogeneity, and critic al current densities for a certain neutron fluence. We have found that the optinum neutron fluence for irradiation is 4.98 x 10(21) m(-2).
