Abstract

A 50-m long, biaxially textured NiO buffer layer for epitaxial growth of YBa2Cu3O7-δ (YBCO) film has been fabricated on a long length cube-textured Ni tape using surface-oxidation epitaxy (SOE) technique. The thickness of NiO layer was arranged to be around 3 μm. The tape manufacturing speed was 15 m/h. The SOE-NiO layer was highly (100) oriented and the full width at half maximum from X-ray φ-scan for NiO(111) was varied from 13 to 19 degrees in the whole length. Jc values exceeding 0.3 MA/cm2 at 77K and self field have been obtained in short samples of YBCO films on NiO/Ni tapes, by using thin MgO cap layer with the thickness of about 100 nm. Crystal orientation control of YBCO coated conductors by SOE method is very effective even for the long length Ni tapes.
