Abstract
The microwave surface resistance of crystals of YBa2(Cu(1-x)M(x))(3)O- 7-delta, with M being Ni or Zn, has been systematically studied at 34. 8 GHz. Both Zn (x=0.0015 and 0.0031) and Ni (x=0.0075 and 0.0140) impu rities were found to be capable of lowering the surface resistance, an d also substantially altering its temperature dependence. The results suggest that the microwave loss of high temperature superconducting th in films might be improved by slightly doping the material with impuri ties.
