Abstract
The microwave response of YBa2Cu3O7/LaAlO3 (YBCO/LAO) and YBa2Cu3O7/MgO (YBCO/MgO) superconducting thin films was studied by microstrip resonator technique. Microwave characteristics of the superconducting films were analyzed by the temperature dependence of resonant frequency, load quality factor and insert loss. The penetration depth at 0K can be attained as: λ0=265 nm for YBCO/LAO and λ0=280 nm for YBCO/MgO. The microwave surface resistance Rs of YBCO/LAO and YBCO/MgO was also investigated by microstrip resonator.
