Flux-pinning behaviors and mechanism according to dopant level in (Fe, Ti) particle-doped $$\text {MgB}_2$$ MgB 2 superconductor [PDF]

Scientific Reports, 2021
We have studied flux-pinning effects of $$\text {MgB}_2$$ MgB 2 superconductor by doping (Fe, Ti) particles of which radius is 163 nm on average. 5 wt.% (Fe, Ti) doped $$\text {MgB}_2$$ MgB 2 among the specimens showed the best field dependence of ...

Electrical transport and pinning properties of Nb thin films patterned with focused ion beam-milled washboard nanostructures [PDF]

New Journal of Physics, 2012
A careful analysis of the magneto-transport properties of epitaxial nanostructured Nb thin films in the normal and the mixed state is performed. The nanopatterns were prepared by focused ion beam (FIB) milling.
