Unified scaling law for flux pinning in practical superconductors: I. Separability postulate, raw scaling data and parameterization at moderate strains*
TL;DR: In this paper, the authors introduced the unified scaling law (USL) for the flux-pinning force per unit conductor length in practical high-field superconductors, where K(t,?0) is a temperature-and-strain dependent prefactor.

A probe for investigating the effects of temperature, strain, and magnetic field on transport critical currents in superconducting wires and tapes
TL;DR: In this article, a variable-temperature probe has been developed to study the effect of strain on the transport properties of superconducting wires and tapes in high magnetic fields, by soldering it to a thick coiled spring and twisting one end of the spring with respect to the other.

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.
