Journal ArticleDOI
Enhancement of the critical current density and flux pinning of MgB2 superconductor by nanoparticle SiC doping
Shi Xue Dou,Saeid Soltanian,Josip Horvat,Xiaolin Wang,Sihai Zhou,M. Ionescu,Hua-Kun Liu,Paul Munroe,M.J. Tomsic +8 more
TL;DR: In this paper, the performance of nano-SiC-doped MgB2 was investigated for flux pinning. And the results showed that the magnetic Jc is consistent with the transport Jc, which remains at 20'000 A/cm2 even at 10 T and 5 K for the doped sample, an order of magnitude higher than the undoped one.
