Study on CexLa1-xO2 Buffer Layer used in Coated Conductors by Chemical Solution Method

Developing multi-functional single buffer layer is one of the most important challenges for simplification of coated conductors configuration. Laa2doped 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 Ce0.9La0.1O2 film are epitaxially deposited on the textured NiW substrate. The 120nm thickness Ce0.9La0.1O2 film is obtained though multi-coating route. The YBCO film with Tco=90.5K￡ which is deposited on Ce0.9La0.1O2/NiW metallic template by PLD method. It suggects that Ce0.9La0.1O2 film prepared by chemical solution route have a promising prospect for the simplification of coated conductors configuration.
