摘要
采用脉冲激光加辅助离子源的方法在长为6.0 cm的NiCr合金基带上制备0.13 μm厚的Y-ZrO2(YSZ)隔离层,再用脉冲激光在YSZ/NiCr带上制备1.5 μm厚的YBa2Cu3O7-x超导厚膜形成YBCO/YSZ/NiCr超导带材。实验测得在77 K,0 Tesla下其临界电流密度为8.75×104 A/cm2,超导转变温度为88.6 K。
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.
