Abstract
Experiments on the irradiation-induced suppression of the critical
temperature in high-Tc superconductors are analyzed within the mean-field
Abrikosov-Gor'kov-like approach. It is shown that the experimental data
for YBa2Cu3O7-δ single crystals can be quantitatively
explained by the pair breaking effects under the assumption of the combined
effect of potential and spin-flip scattering on the critical temperature and
with account for a non-pure d-wave superconducting order parameter.
