Abstract： BaTiO3(BTO)/YBa2Cu3O7 (YBCO) heteroepitaxial films have been fabricated on (100) SrTiO3 substrates by pulsed laser ablation. X-ray characterizations show the BTO/YBCO bilayer films have a highly epitaxial nature. Rocking curves for the BTO (002) and YBCO (005) peaks have full width at half maximum values of 0.36°and 0.32°, respectively. The Ф scan plots indicate good in-plane alignments of these epitaxial films. The ferroelectric properties of the B TO/YBCO heteroepitaxial films were evaluated by capacitance-voltage measurement in metal-ferroelectric-metal configuration.
