Abstract

We have studied the effects of oxygen defects in CuO₂ planes by 80 keV electron irradiation on YBCO thin films. Similar to the results of Zn-doped YBCO, a significant increase in residual resistivity accompanies T_c suppression, and the relation could be described in the framework of pair-breaking. However, the T_c suppression rate is three times as slow as predicted by d-wave pairing symmetry. For irradiated samples, (dH_c2/dT) near T_c is consistent with the scenario of double pair-breaking, in contrast to the case of Pr-doped YBCO.
