MOCVD of buffer Layers and Superconducting Layers on moving textured nickel tapes

Buffer layers and YBCO have been continuously deposited on textured Ni5%W tapes in a reel-to-reel MOCVD system. The buffer layers were perovskites with the composition (AA')(BB')O/sup 3/ (A, A'=La, Sr, Ca, Ba and B, B'=Cr, Mn, Fe, Co, Ni). The buffer layers were well textured with in-plane FWHM down to 5.5/spl deg/ and out-of-plane FWHM down to 2.2/spl deg/.
