Fully c-axis-oriented YBCO films were directly deposited on polycrystallinesilver substrates by inclined substrate pulsed laser ablation. The orientationand microstructure of the YBCO films were characterized by x-raydiffraction 2θ-scans,Ω-scans and pole figure analysis. Surface morphologywas examined by scanning electron microscopy. Irregular-mosaic-shapedsupergrains were observed in the films. Raman spectroscopy was used toevaluate the quality of the YBCO films. The superconducting transitiontemperature (Tc) and the critical current density (Jc) of the films weredetermined by inductive and transport measurements, respectively. Tc=91K with sharp transition and Jc=2.7×105 A cm−2 at 77K in zero fieldwere obtained on a film that was 0.14μm thick, 5mm wide and 10 mmlong. This work demonstrated a promising approach to obtain high-JcYBCO films on nontextured polycrystalline silver substrate.
