Abstract
Epitaxial YBa2Cu3O7-δ (YBCO) films with transport critical current densities approaching 3 × 106 A/cm2 (77K, 0T) 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 (∼0.2μm)/YSZ (0.7μm)/CeO2 (0.05μm)/Ni (125μm). 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°C and 790°C.
