磁场中的空心超导体(hollowsuperconductorsinmagneticfield)
磁场中空心超导体也分复(多)连通和单连通两类。若在样品实体部分中任取包围贯通样品中空部分回路,从几何上讲回路不能收缩为点是复连通,若有磁通存在也同样是贯通回路的,则对磁通也是复连通,若磁通未贯通回路,则是单连通,其磁行为与单连通空心体类似。例如空心球体,空心椭球体,它们虽有中空部分,但外壳层是封闭的,没有贯通样品的孔,从几何上和对磁通讲均为单连通。又如空心超导圆柱体,虽有贯通柱体的空心部分,几何上是复连通,但在垂直于柱轴的磁场中,薄壁样品磁通穿透进入空腔的横向场与回路面是平行的,磁场未贯通回路,则其磁性质与单连通空心体类似。但若磁场平行于柱轴,则对磁通讲也是复连通的。磁场中的复连通超导体可有量子化的冻结磁通现象。空心超导体随着壁壳层厚度与弱场穿透深度相比拟的厚薄程度不同,其磁性质也有异,即有样品尺寸效应等性质的差异,也有大小两种样品的区分。这些空心超导体(单连通和复连通,大样品和小样品)的宏观性质,包括宏观量子性质,均可用GL理论来进行研究。
