At T = TSC, the identified critical exponents are 尾 = 2/3, 3/4 and 1. The large BC1 and BC2 values indicate that the two Cooper-pair electrons of the type II superconductors are much stronger coupled compared to the type I superconductors, remarkably, without a ...
(cryogenics) A superconductor for which there are two critical magnetic fields; magnetic flux is completely excluded from the interior of the material only at field strengths below the smaller critical field, and at field strengths between the two critical fields the magnetic flux consists of flux...

In the usual Ginzburg-Landau theory the critical value of Ginzburg-Landau parameter kappa(c) = 1/root 2 separates regimes of type-I and type-II superconductivity. The latter regime possess thermodynamically stable vortex excitations which interact with e

We demonstrate the existence of a novel superconducting state in high quality two-component MgB2 single crystalline superconductors where a unique combination of both type-1 (kappa_1 < 0.707) and type-2 (kappa_2 > 0.707) superconductor conditions is realized for the two components of the order...
aMagnetic flux penetrates type-Ⅱ superconductors in the form of Abrikosov vortices that arrange to a more or less regular flux-line lattice (FLL) which is pinned by inhomogeneities of the material. If the local current density j exceeds a critical value j, 磁性焊剂击穿类型Ⅱ superconductors以安...
Superheating Field of Type II Superconductors 来自 Semantic Scholar 喜欢 0 阅读量: 38 作者:Chapman,S Jonathan 摘要: The superheating magnetic field of a type II superconductor is examined, using the time-dependent Ginzburg-Landau equations and the methods of formal asymptotics. The superconducting ...
This chapter addresses the following topics: The history of the discovery of Type II superconductors and their usual magnetic properties: two critical fields and the mixed state in between, with a partial penetration of the magnetic field in the form of
We show that in multiband superconductors even small interband proximity effect can lead to a qualitative change in the interaction potential between superconducting vortices by producing long-range intervortex attraction. This type of vortex interaction results in unusual response to low magnetic fields ...
