摘要:

研究了单个亚微米高温超导体(HTS)环的特性。观察到的Little-Parks效应,并伴随着一个异常的行为的磁电阻的依赖性,我们归因于非均匀的涡(超流角动量)内的环臂。这种效应与相干长度值和伦敦渗透深度之间的特殊HTS关系有关。

英文摘要:

The properties of single submicron high-temperature superconductor (HTS) rings are investigated. The Little-Parks effect is observed and is accompanied by an anomalous behavior of the magnetic dependence of the resistance, which we ascribe to non-uniform vorticity (superfluid angular momentum) within the ring arms. This effect is linked to the peculiar HTS-relationship between the values of the coherence length and the London penetration depth.
