Second magnetization peak effect, vortex dynamics, and flux pinning in 112-type superconductor Ca0.8La0.2Fe1−xCoxAs2
Investigation of vortex pinning and its relaxation is of great importance for both basic physics and technological applications in the field of superconductivity. We report a great improvement of superconducting properties in the recently discovered 112-type superconductors (Ca, La)FeAs2 through Co co-doping. High critical current density Js(5 K) > 2(*)10(6) A/cm(2) is obtained and pronounced s...

متن کاملModel for vortex pinning in a two-dimensional inhomogeneous d-wave superconductor
We study a model for the pinning of vortices in a two-dimensional, inhomogeneous, type-II superconductor in its mixed state. The model is based on a Ginzburg-Landau GL free energy functional whose coefficients are determined by the mean-field transition temperature Tc0 and the zero-temperature penetration depth 0 . We find that if i Tc0 and 0 are functions of position and ii 2 0 Tc0 y with y 0,...
متن کاملFlux Pinning and Forced
We propose controlled splay of artiicial columnar defects in cuprate super-conductors as a strategy to enhance transport properties in a eld compared to parallel columns. The theory predicts a new \splayed glass" phase characterized by a reduced ux creep, an entangled ground state, and an astronomically slow response to an applied transverse eld.
متن کاملEnhancement of the critical current density and flux pinning of MgB2 superconductor by nanoparticle SiC doping
Doping of MgB2 by nano-SiC and its potential for the improvement of flux pinning were studied for MgB22x(SiC)x/2 with x50, 0.2, and 0.3 and for 10 wt % nano-SiC-doped MgB2 samples. Cosubstitution of B by Si and C counterbalanced the effects of single-element doping, decreasing Tc by only 1.5 K, introducing intragrain pinning centers effective at high fields and temperatures, and significantly e...
