Abstract

Analysis of the propagation of surface acoustic waves (SAW) was carried out in piezoelectric-high-temperature superconductor (HTSC) film-dielectric structure near the superconducting transition of the HTSC film. By considering a change in the resistive state of the film, its inhomogeneity in a direction perpendicular to the substrate, and the mechanical load of the piezoelectric, equations describing the temperature dependence of the velocity and attenuation of the SAW were obtained. Our calculations agree with experimental results for LiNbO3-YBa2Cu3O7 structures if possible inhomogeneities in the film are taken into account.
