Guanmei W and Damian P Hampshire The cause of ‘weak-link’ grain boundary behaviour in polycrystaliine Bi2212 and Bi2223 superconductors. SuST 31 (2018) 024001 . Open Access. First (quantitative paper) calculations and measurements showing how resistive grain boundaries must be to limit Jc in Bi- HTS polycrystalline superconductors. Here we show: Bi-2212 has low grain boundary resistivity and hence potential for high Jc if grain and grain-boundary pinning is added; Bi2223 must be aligned to increase Jc.

How resistive must grain boundaries in polycrystalline superconductors be, to limit Jc? – SUST 20 104001 (2017) Open Access First (quantitative paper) calculations and measurements showing how resistive grain boundaries must be to limit Jc in polycrystalline superconductors. Here we show: Jc values in state-of-the-art technological high-field superconductors are only 1 % of theoretical limit; Large increases in Jc may be achieved in Nb3Sn, by completely removing the grain boundaries from these materials.
