Abstract
The temperature dependence of the microwave surface resistance for overdope d YBa2Cu3O7-delta films has been investigated experimentally. It was shown that the observed unusual behavior of the surface resistance can be describ ed in the framework of the spin-flip scattering of carriers, leading to the pair breaking and the subsequent recovery of superconductivity caused by t he ordering trend of the magnetic impurities at low temperature. A simple p henomenological model based on the common BCS approach is suggested, which is able to interpret nicely the experimental data.
