Abstract

While nonsuperconducting particles are known to serve as effective pinning centers in conventional superconductors, their effect in high T_c superconductors is still controversial. In this paper, we give evidence that nonsuperconducting Y₂BaCuO₅ (211) inclusions can act as pinning centers in melt processed YBaCuO superconductors even when their size is orders of magnitude larger than the coherence length.
