EPITAXIAL GROWTH OF BUFFER LAYERS AND YBCO FOR COATED CONDUCTOR

Abstract

An Y 2 O 3 film, as seed layer, was directly deposited on the meter long length rolling assisted biaxially textured substrate (RABiTS) NiW tapes by the reactive magnetron sputtering process. Yttria stabilized zirconia (YSZ) and CeO 2 films were further carried out as the barrier and cap layers, and YBCO layer was prepared by magnetron sputtering technique as well. X-ray diffraction was employed to characterize the texture of film. The results showed that on NiW tapes highly textured films were obtained.
