Observation of record flux pinning in melt-textured NEG-123 superconductor doped by Nb, Mo, and Ti nanopaticles

Original language description

Doping of the ternary NEG-123 superconductor by Nb2O5, MoO3 and TiO3 nanoparticles led to record values of the critical current density giving evidence of up to now most effective vortex pinning in bulk superconductors. The optimum concentration of all three dopands was 0.1 mol% in the Nb2O5 doped sample the remnant Jc achieved 925 kA/cm2 at 65 K, 640 kA/cm2 at 77 K, and 100 kA/cm2 at 90.2 K. This enables a steady levitation up to vicinity to the critical temperature of this material.
