摘要：

The low-temperature dependence of the microwave complex surface impedance (17 GHz) of pure and Zn-doped high-quality YBCO single crystals is reported. The surface resistance of the pure crystal shows a peaked structure around 40 K which disappears with Zn doping. The in-plane penetration depth varies linearly with temperature below 25 K; a T2 contribution appears at the lowest temperature when Zn impurities are added. This suggests that the former temperature dependence is intrinsic to pure crystals whereas the T2 behavior, also observed in thin films, would be due to defects. The linear temperature dependence is expected for superconducting gaps with lines of nodes.
