补充资料:超导体小样品(smallspecimensofsuperconductors)
超导体小样品(smallspecimensofsuperconductors)

一般称超导体某一尺度d≤δ0的样品为超导体小样品,δ0是弱磁场穿透深度,d可表示为平板或薄膜的半厚度和圆柱体包球体的半径等。在有附加条件d<ξ时(ξ为相干长度),则不论第一类和第二类超导体,大样品的中间态,混合态和表面超导电性,对小样品言就难于形成或不存在,所以大样品的三个临界磁场Hc1,Hc2和Hc3对小样品言也失去原有的含义。对应第一类超导体的相变临界场Hc,小样品的相变临界场现用HK1来表示。理论和实验均证实,对单连通超导体的HK1比Hc要高,甚至高很多,金兹堡(Ginzburg)将`(Kd//\delta_0)^2\lt\lt1`的样品视为小样品,K是GL参量,理论给出存在样品的临界尺寸dK。d<dK时,在HK1的超导-正常相变为二级相变的样品尺寸分界。在一级相变情形中,当H逐渐增加至HK2>H>HK时,还可存在亚稳的超导相(态),称超导态的过热相,简称过热态;而当H逐渐减小至HK1<H<HK时,还可存在亚稳的正常相(态),称正常态的过冷相,简称过冷态。在亚稳相区均称滞后现象。这里HK2和HK1现在分别称过热临界磁场和过冷临界磁场,HK称平衡相变临界磁场,是一级相变。H>HK2时样品整体处于正常态(相),H<HK1时处于超导态(相)。对超导体小样品的电磁性质一般用GL理论来研究。
