Condensed matter physics Depairing Current Density in Cuprate Superconductors UNIVERSITY OF SOUTH CAROLINA Milind N. Kunchur LiangManlaiWe report a study of the depairing critical current density in the electron-doped infinite-layer Sr1-xLaxCuO2 and Nd2-xCexCuO4-\\delta system. In this work, ...
In particular, we observe an unexpectedly large pinning strength for perpendicular vortex flux across the boundary, which implies that the critical current that can be supported along the boundary approaches the theoretical `depairing' limit.doi:10.1038/37312Ivan MaggioAprile...
depairing currentMeissner stateSuperconductors are essential in many present and future technologies, from large-scale devices for medical imaging, accelerators, or fusion experiments to ultra-low-power superconducting electronics. However, their potential applicability, and particularly that of high-...
It is found that the depairing current densities in both cases are higher than those predicted by Tinkham. One of the reasons for the higher current densities is that those are obtained at the transition point to the normal state, while Tinkham obtained in the superconducting state far from ...
In superconductor/ferromagnet (S/F) hybrids the order parameter induced in the F-layer due to the proximity effect is spatially inhomogeneous. This could result in the nonmonotonic behavior of the critical temperature T c and the depairing current density J dp as a function of the thickness ...
This could result in the nonmonotonic behavior of the critical temperature T c and the depairing current density J dp as a function of the thickness of the ferromagnet d F .doi:10.1007/978-1-4020-5107-4_12A.Yu. RusanovJ. Aarts

The effect of the demagnetizing factor, regarding the determination of the de-pairing current density J d e p , has been studied in the case of a Fe(Se,Te) crystal, using DC magnetic measurements as a function of a magnetic field (H) at different temperatures (T). Firs...
The depairing current is directly measured and is in good accordance with the values predicted by Ginzburg-Landau theory. In intense currents the critical temperature is not only shifted to lower temperatures, as seen in conventional d.c. measurements, but the shape of the transition changes ...
The typical approach to increasingJcis to introduce defects to control dissipative vortex motion. However, when optimized, this approach is theoretically predicted to be limited to achieving a maximumJcof only 30% of the depairing current densityJd, which depends on the coherence length and the ...
