| Popis: | The surface resistance of viscous processed and powder processed bulk polycrystalline YBa/sub 2/Cu/sub 3/O/sub 7-X/ specimens have been measured as a function of frequency (27-38 GHz) and temperature (10-150 K) using an endwall replacement technique. The surface resistance of the viscous processed material within the 9-38 GHz frequency region gives a crossover frequency of 7.6 GHz. The temperature dependence of the superconducting state of material from both processing methods can be described by a two-gap BCS model which treats the sample as a network of weakly coupled superconducting grains. > |
