Abstract

Strongly in-plane aligned, c-axis oriented YBCO films were successfully grown on polycrystalline nickel tapes buffered with (lOO)-oriented NiO layers. The in-plane and out-of-plane alignments of the NiO layer were achieved by a surface-oxidation epitaxy (SOE) technique using a {100}<001> cube-textured nickel tape. The in-plane textures of NiO layers fabricated so far with the full width half maximum (FWHM) values of 11-13 degrees are sufficient tor the epitaxial growth of high-./; YBCO films. Pulsed laser deposited YBCO layers on the NiO/Ni tapes were not only c-axis oriented with respect to the tape surface, but also strongly in-plane aligned. The YBCO films on NiO/Ni tapes have a zero resistance Tc =87K and Jc=104-105A/cm2 at 77K.
