Abstract
Piezoelectric PbTiO3 films with preferred c-axis orientation were fabr icated on MgO substrates by RF-sputtering method. By using a fabricate d interdigital electrode, surface acoustic waves (SAWs) with a frequen cy of 192 MHz were propagated on PbTiO3 film/MgO substrate and on supe rconducting Bi(Pb)(2)Sr2CaCu2OF film/PbTiO3/MgO substrate. The tempera ture dependence of the SAW attenuation coefficient was investigated be low room temperature.
