Strong Pinning Enhancement in MgB2 Using Very Small Dy2O3 Additions
S. K. Chen, M. Wei, J. L. MacManus-Driscoll
0.5 to 5.0 wt.% Dy2O3 was in-situ reacted with Mg + B to form pinned MgB2. While Tc remained largely unchanged, Jc was strongly enhanced. The best sample (only 0.5 wt.% Dy2O3) had…

Strong influence of boron precursor powder on the critical current density of MgB2
S. K. Chen, K. A. Yates, M. G. Blamire +1
The influence of the nature of the boron precursor on the superconducting properties of polycrystalline MgB2 was studied. Critical current densities for the MgB2 made from high pur…

Improved Current Densities in MgB2 By Liquid-Assisted Sintering
S. K. Chen, Z. Lockman, M. Wei +2
Polycrystalline MgB2 samples with GaN additions were prepared by reaction of Mg, B, and GaN powders. The presence of Ga leads to a low melting eutectic phase which allowed liquid p…
