Study of Magnetic Flux Pinning in Nb-Ti Superconductors Using Artificial Pinning Center Technology
Multifilamentary Nb-Ti superconducting wires with heterogenous flux pinning nano-structures have been fabricated using artificial pinning center (APC) technology. Pinning centers were introduced into Nb-Ti filaments, consisting of Cu-Ni, Nb and Nb+Ti rods with the triangular arrangement and the volume fraction of 17 %. After final hot extrusions, the APC wires were drawn down over a high strain...
متن کاملPinning phenomena in a superconducting film with a square lattice of artificial pinning centers
We study the transport properties of a superconducting Nb film with a square lattice of artificial pinning centers (APCs) as a function of dc current, at a temperature close to the superconducting transition temperature of the film. We find that, at low dc currents, the differential resistance of the film shows the standard matching field anomaly, that is, the differential resistance has a loca...
متن کاملQuantification of Pinning Center Thickness in Conventionally
The quantity, size and distribution of pinning centers are key factors in determining the Jc of Nb-Ti-based superconductors. In Artificial Pinning Center, APC composites large strains must be applied between the assembly of the pinning structure and the final strand, which can result in large changes and variations in pinning center size and shape. In order to correctly interpret the properties...
متن کاملSuperconducting vortex pinning with artificial magnetic nanostructures
This review is dedicated to summarizing the recent research on vortex dynamics and pinning effects in superconducting films with artificial magnetic structures. The fabrication of hybrid superconducting/ magnetic systems is presented together with the wide variety of properties that arise from the interaction between the superconducting vortex lattice and the artificial magnetic nanostructures....
