Irradiation-induced suppression of the critical temperature in high-Tc   superconductors: Pair breaking versus phase fluctuations
  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 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.
