| Abstract: | CeO2/YSZ/CeO2 buffer layers were deposited on textured Ni substrates by in situ pulsed laser deposition. The out-of-plane texture and in-plane texture of the buffer layers were characterized by X-ray diffraction
ω-scans and ϕ-scans. Using this CeO2/YSZ/CeO2 architecture as the buffer layers, high quality YBCO films with a zero-resistance T
c about 90 K and a self-field critical current densities J
c above 106 A/cm2 at 77 K can be obtained on Ni substrates. |
