High Jc YBCO coated conductors on non-magnetic metallic substrate using YSZ-based buffer layer architecture

摘要: Abstract Biaxially aligned YBa2Cu3O7−δ (YBCO) thick films were deposited by pulsed laser ablation technique on cube textured non-magnetic Ni89V11 (Ni–V) substrate, using CeO2/YSZ/CeO2/NiO buffer layer architecture. The first NiO seed was formed epitaxial oxidation of the Ni–V substrate. Structural analyses show typical full width at half maximum values φ- and ω-scans less than 10° 8°, respectively. highest value obtained for critical current density 77 K zero magnetic field 6×105 A cm−2, which is close to that YBCO grown CeO2/NiO
