摘要：

Double-sided Y1Ba2Cu3O(x) films are prepared on MgO(100) substrates for KrF excimer laser deposition and their electrical properties, both direct current and microwave frequencies, are examined. Double-sided Y1Ba2Cu3O(x) films show zero resistivity at temperatures higher than 88 K and rho(300K)/rho(100 K) higher than 2.7. Using a niobium shield, a double-sided Y1Ba2Cu3O(x) films microstrip line resonator at 5.7 GHz shows an unloaded Q value of 2.6 x 10(4) at 77 K and 1.1 x 10(5) at 4.2 K. These are the highest class of unloaded Q known to be reported for planar-type resonators.
