The upper critical field of filamentary Nb3Sn conductors
A. Godeke, M. C. Jewell, C. M. Fischer +3
We have examined the upper critical field of a large and representative set of present multi-filamentary Nb3Sn wires and one bulk sample over a temperature range from 1.4 K up to t…

High-field superconductivity in alloyed MgB2 thin films
V. Braccini, A. Gurevich, J. E. Giencke +24
We investigated the effect of alloying on the upper critical field in 12 films, in which disorder was introduced by growth, carbon doping or He-ion irradiation, fi…
