| 摘 要： | 系统研究了表面镀镍的Bi2223多芯带材的临界电流特性。实验表明,经过镀镍处理的Bi2223带材的临界电流可提升10%左右。为了更好的说明铁磁环境对于临界电流的影响,建立了有限元模型,定量研究了外加磁场下不同涂覆参数对于临界电流的影响。

| Abstract: | Critical current of the ferromagnetic coated (FC) tape is systematically studied. It shows that the maximum critical current of the FC tape enhanced by 10%. In order to investigate the effect of ferromagnetic coating on the critical current, a finite element analysis model is built to quantitatively evaluate the independence of the coating parameter to the performance of the tape. The effect of external fields and different ferromagnetic material on critical current are taken into account. |
