Abstract

Various changes in the microwave absorption signals of irradiated samples of different quality YBa2Cu3O7 and Tl2CaBa2Cu2O8 target materials by lowdose (1014 n/cm2) monoenergetic neutrons have been observed and studied. The irradiation induced changes of the shape of microwave absorption lines together with transport measurements show that the low-dose irradiation in poor quality samples increases, while in good quality ones, decreases the superconducting volume fraction. Low quality (non-percolative) samples are more sensitive to irradiation than the high quality ones. These observations indicate that the consequences of irradiation are determined mainly by the preirradiation structure of the samples.
