Abstract
YSZ films have been widely used as buffer layers for high T/sub c/ superconductor. However, it is necessary to investigate and develop another buffer layer with suitable, simple, and neat processing. Films of Ce-Zr mixed oxide were deposited by rf and dc magnetron co-sputtering. In sputtering process, dc power of Zr was fixed in 200 W while rf power of Ce was varied with 30 W, 50 W, 100 W, respectively. As-deposited (Ce/sub x/Zr/sub 1-x/)O/sub 2/ films were crystallized without post annealing. It was confirmed that the composition of the films could be controlled with controlling rf power of Ce target. The /spl Phi/ scan of XRD showed that all (Ce/sub x/Zr/sub 1-x/)O/sub 2/ films were [200] c-axis oriented. Three consecutive magnetron sputtering procedure for seed, CZO and cap layer for HTSC films using Ce, Zr and CeO/sub 2/ target were carried out on the Si[100] and Ni substrate successfully. It is suggested that sputtered and c-axis oriented (Ce/sub x/Zr/sub 1-x/)O/sub 2/ films can be a potential candidate to replacing YSZ buffer layer.
