Notes:
CeO2 has been considered as one of the most lattice compatible and chemically stablematerials for YBa2Cu3O7-x coated conductors. In this paper, we presented the epitaxial growth ofCeO2 thin film on both YSZ single crystal and cube textured Ni5W substrates by MOD method.Homogenous, crack-free and dense CeO2 thin films on both substrates with sharp biaxially cubetexture were fabricated by post-annealing the precursor films at 1000-1150°C. For the CeO2 film onthe textured Ni5W substrate, the FWHM values of (111) Phi-scan and (002) rocking curve werearound 6°and 7°, respectively, the surface roughness was less than 2 nm over an area of 1μm×1μmobserved by AFM. It was found that the CeO2 thin film improved both the in-plane orientation andsurface roughness of the Ni5W substrate, indicating that the as deposited CeO2 films were suitablefor the further growth of YBCO superconductor layer
