摘要
高温超导体磁通钉扎机制一直是高温超导领域的研究热点。根据D.Dew-Hughes理论模型,提出了一种简化的磁通钉扎力密度表达方式。结合文献中给出的实验数据,采用曲线拟合的方法基本可以确定Bi-2223的磁通钉扎类型,模拟研究的结果与实际情况比较吻合。
Flux pinning mechanism of high temperature superconductors is a research hotspot at all times. To analyze the pinning mechanism in Bi-2223 high temperature superconductors, a predigestion formula of pinning has been founded according to D,Dew-hughes model. In accordance with the experimental data of the references, the pinning mechanism in Bi-2223 high temperature superconductors was confirmed by curve fitting. The result of simulation proves to be consistent with the conclusion of the references.
