Flux-Pinning Behaviors and Mechanism According to Dopant Level in (Fe, Ti) Paticle-Doped MgB${}_2$ Superconductor

H. B. Lee, G. C. Kim, Young Jin Shon +2

We have studied flux-pinning effects of MgB${}_2$ superconductor by doping (Fe, Ti) particles of which radius is 163 nm on average. 5 wt.\% (Fe, Ti) doped MgB${}_2$ among the specimens…
