摘要: CeO$_{2}$/YSZ/CeO$_{2}$ buffer layers were deposited on biaxially textured Ni substrates by pulsed laser deposition. The influence of the processing parameters on the texture development of the seed layer CeO$_{2}$ was investigated. Epitaxial films of YBCO were then grown \textit{in situ} on the CeO$_{2}$/YSZ (yttria-stabilized ZrO$_{2}$)/CeO$_{2}$-buffered Ni substrates. The resulting YBCO conductors exhibited self-field critical current density $J_{\rm c}$ of more than 1 MA/cm$^{2}$ at 77K and superconducting transition temperature $T_{\rm c}$ of about 91K.
