Fig.1 Flux penetration in YBCO sample doped with Y2O3 nanoparticles in dynamic (5mT field and 1 Amp current) and static case (48mt field) respectively.

In High Tc superconductors, the movement of magnetic fluxons reduces the higher supercurrent and hence, its potential applications. A higher critical current density can be achieved by doping of nanoparticles as a pinning center for the magnetic fluxons. We study the effect of doping of various types of nanoparticles on the flux dynamics using TRMOI Technique.
