Abstract

A study regarding the epitaxial growth of Y₂O₃ film on textured metal substrate and its use as a single buffer layer of a YBCO coated conductor is reported. Different deposition conditions were employed and compared in order to obtain good epitaxial Y₂O₃ film followed by deposition of YBCO superconducting films. The YBCO film deposited by PLD on top of the Y₂O₃ films has good microstructure and superconducting properties. The effect of the thickness of Y ₂O₃ film on the texture of Y₂O₃ film and the critical current density (J_c) of YBCO film deposited on top of that were analysed. The J_c of YBCO films on Y ₂O₃/Ni and Y₂O₃/NiW were 1.0 × 10⁶ A cm^-2 and 1.1 × 10⁶ A cm^-2 at 77 K and self-field respectively, which indicated that Y ₂O₃ is a suitable candidate as a single buffer layer for the fabrication of a YBCO coated conductor.
