Microscopic origin of the abnormal elastic behavior accompanying the superconducting transition in Nb3Sn crystals: an extended ab initio study
TL;DR: In this article , an analytical model for depicting the abnormal temperature-dependent elastic constants and transition resistivities of superconducting Nb3Sn is proposed, which takes into account the interaction of the d electrons with the strain, the strain-modulated electronic structure evolution and the accompanied variations in the density of states at the Fermi level.

Effect of strain on critical magnetic field in type-II superconductors
TL;DR: In this paper, the authors studied the strain effect on critical magnetic field in isotropic high-κ superconductors and derived the critical magnetic fields in the presence of the applied strain.

Flux vortices and transport currents in type II superconductors
A. M. Campbell,J. E. Evetts +1 more
TL;DR: In this paper, the authors considered the effects of lattice rigidity on the summation of pinning forces and showed that a summation based on statistical arguments uses the same approximations and leads to the same results as a dissipation argument.

Scaling laws for flux pinning in hard superconductors
TL;DR: In this paper, it was shown that the peak in Fp scales as [Hc2(T)]2.5 if the temperature is changed; the maximum value of Fp occurred at the same value of reduced field regardless of temperature.

Flux pinning mechanisms in type II superconductors
TL;DR: In this article, expressions for flux-pinning in type II superconductors are derived from considerations of the nature of the interaction between individual flux-lines and pinning-centres, and of the geometry of th...

Hysteresis in Superconducting Alloys-Temperature and Field Dependence of Dislocation Pinning in Niobium Alloys
W. A. Fietz,W. W. Webb +1 more
TL;DR: In this paper, critical current and pinning-force densities in a series of niobium alloys subjected to severe plastic deformation have been determined from measurements of complete hysteretic magnetization curves on alloys with Ginzburg-Landau parameter $\ensuremath{\kappa}$ between 1.3 and 13 at temperatures from the critical temperature ${T}_{c}$ down to $0.14{T}

Elastic energy of the vortex state in type II superconductors. I. High inductions
TL;DR: In this article, the elastic properties of the flux line lattice (FLL) in type II superconductors are calculated from the linearized Ginzburg-Landau (GL) theory for large inductions.
