We report on the growth of epitaxial YBa 2Cu 3O 7 thin films on X-cut LiNbO 3 single crystals. The use of double CeO 2/YSZ buffer layers allows a single in-plane orientation of YBa 2Cu 3O 7, results in superior superconducting properties. In particular, surface resistance R s values of 1.4 m have been measured at 8 GHz and 65 K. The attainment of such low values of R s constitutes a key step toward the incorporation of high T c materials as electrodes in photonic and acoustic devices. © 2002 American Institute of Physics. © 2002 American Institute of Physics.
