| Abstract: | The buffered layer Y-ZrO 2 (YSZ) was deposited on the flexible metallic NiCr substrate tape of 6.0 cm in length by a KrF laser and ion beam assisted deposition (IBAD), and then YBCO superconducting thick films were deposited on the YSZ/NiCr in order to obtain a high current density YBCO superconducting tape for power applications. The thickness of 1.5 μm and 0.13 μm is for the YBCO and the YSZ, respectively. The critical current density of YBCO/YSZ/NiCr is 8.75×10 4 A/cm 2 at 77 K, 0 Tesla, the cirtical temperature is 88.6 K. |
