Abstract

CeO2//YSZ//YBCO layers have been successfully grown on rolling-assisted biaxially textured Ni(001) substrates using pulsed laser deposition. The results indicate that CeO2 and YSZ can effectively improve film texture. The full-width at half-maximum (FWHM) of the rocking curves for Ni(002), CeO2(002), YSZ(002) and YBCO(005) are 10.8°, 6.8°, 4.7°, 1.2°, respectively. The FWHM of φ-scans for CeO2(202) and YBCO(226) are respectively 9° and 6.5°. Scanning electron microscopy observations reveal that the layer-like morphology was evident from all layers, and Ag can effectively fill in the microcracks and prevent interdiffusion. The critical current density of the best films is 1-2 × 106 A/cm2.
