Superconducting YBa2Cu3O7−δ thin films with Tc=89.5 K were deposited on MgLaAl11O19 (11¯0) substrates by pulsed laser deposition. X-ray diffraction patterns indicate that the YBa2Cu3O7−δ films were epitaxial films, with the c axis perpendicular to the substrate surfaces. Microstrip resonators of YBa2Cu3O7−δ thin films deposited on MgLaAl11O19 substrates were fabricated. The loaded quality factor of the resonator was 1007 at 77 K and 4.28 GHz. As a new substrate for high Tc oxide superconducting films, MgLaAl11O19 substrates are especially suitable for superconducting-microwave applications.
