Suppression of flux jumps in high-$J_c$ Nb${}_3$Sn conductors by ferromagnetic layer

Cun Xue, Kai-Wei Cao, Tian He +3

Flux jumps observed in high-$J_c$ Nb${}_3$Sn conductors are urgent problems to construct high field superconducting magnets. The low-field instabilities usually reduce the current-ca…
