  • Abstract
    Reports on quality factor measurements of a coplanar waveguide transmission line resonator patterned from a YBa2Cu3O7-x film on a LaAlO3 substrate, resonating at 6.5 GHz. At 77 K the unloaded quality factor is 3850+or-180, that is about 43 times higher than that of an identical copper resonator at the same temperature and frequency. This result demonstrates the usefulness of LaAlO3 as a substrate for high-temperature superconducting microwave applications.
