LEVITATION FORCE PROPERTY AND TRAPPED FIELD OF HTS GdBaCuO BULK SUPERCONDUCTOR

本文对φ20mm,φ30mm的GdBaCuO超导块材在液氮温区的磁悬浮特性及捕获磁通进行了研究,77K零场冷条件下,GdBaCuO超导块材磁悬浮力密度在2～10N/cm2.对不同Gd211含量的GdBaCuO超导块材的磁悬浮力和捕获磁通性能进行了对比,发现对φ30mm的样品,40%molGd211(Gd1.8)的GdBaCuO超导块材捕获磁通性能最高.同时对比了GdBaCuO和YBCO超导块材的磁悬浮力和捕获磁通性能,结果表明GdBaCuO与YBCO超导块材在相同的磁悬浮力性能下,捕获磁通性能大于YBCO超导块材.
