摘要：

Biaxially aligned (triaxially aligned) YSZ thin films were formed on polycrystalline substrates by ion-beam assisted deposition (IBAD). The biaxial aligning of YSZ was much affected by the incident angle of the assisting ion-beam toward the substrate. In-plane aligned YBCO thin films were deposited by laser ablation on polycrystalline substrates, Hastelloy alloy, with biaxially aligned YSZ thin films as the buffer layers. Jc-B characteristics of these YBCO thin films were improved in one order of magnitude, compared with ones buffered with conventionally sputtered YSZ, and high Jc values of 10(5) A/CM2 (77K, OT) range stable for many times were obtained. The small mis-orientation angles at grain boundaries of in-plane aligned YBCO thin film along a- and b-axes were observed by TEM.
