Abstract
We have successfully employed metal-organic chemical vapor deposition (MOCVD) technique to simultaneously deposit double-sided YBa2Cu3O7−δ (YBCO) films on both sides of Y2O3/yttria-stabilized zirconia (YSZ)/CeO2 (YYC) buffered biaxially textured Ni-5 at.% W substrates, which is of great prospect to cut the production cost of YBCO coated conductors. X-ray diffraction analysis revealed that both sides of YBCO film were purely c-axis oriented and highly textured. The ω-scan of (005) YBCO and ϕ-scan of (103) YBCO yielded full width at half maximum (FWHM) values of 4.9° and 6.6° for one side of double-sided YBCO film, respectively, as well as 4.4° and 6.4° for the other side. The current transportation measurements performed on such double-sided 500 nm-thickness YBCO films showed the self-field critical current density (Jc) at 77 K of 0.6 MA/cm2 and 1.2 MA/cm2, respectively. Further research is in the process of exploring new solution to improve the Jc in practice.
