摘要：

Epitaxial YBa2Cu3O7-delta (YBCO) films with transport critical current densities approaching 3 x 10(6) A/cm(2) (77 K, 0 T) were fabricated using laser ablation of YBCO onto rolling-assisted biaxially textured-substrates (RABiTS) using a combination of thin CeO2 and thick YSZ buffer layers. The configuration of the sample was YBCO (similar to 0.2 mu m)/YSZ (0.7 mu m)/CeO2 (0.05 mu m)Ni (125 mu m). The CeO2 and YSZ buffer layers were deposited using electron-beam evaporation and sputtering, respectively. The temperature window for successful pulsed-laser deposition of YBCO onto RABiTS was found to be between 740 degrees C and 790 degrees C.
