Abstract

Abstract: Developing multi-functional single buffer layer is one of the most important challenges for simplification of coated conductors configuration. Ladoped CeO₂ films were prepared by chemical solution method. And surface morphology and texture quality of the La-doped CeO₂ films were investigated in details. The results show that the as-obtained pore-free Ce_0.9La_0.1O₂ film are epitaxially deposited on the textured NiW substrate. The 120nm thickness Ce_0.9La_0.1O₂ film is obtained though multi-coating route. The YBCO film with T_co=90.5K， which is deposited on Ce_0.9La_0.1O₂/NiW metallic template by PLD method. It suggects that Ce_0.9La_0.1O₂ film prepared by chemical solution route have a promising prospect for the simplification of coated conductors configuration.

Key words: coated conductors, chemical solution method, doped CeO₂ film, texture
