YBa2Cu307 crystals fabricated by a quench and melt growth process contain fine Y2BaCuO5 particles. These fine precipitates are considered to have three beneficial effects: they suppress crack formation; they promote oxygen diffusion; and they act as pinning centres. Such crystals exhibit larger flux
While non-superconducting particles are known to serve as effective pinning centres in conventional superconductors, their effect in high T c superconductors is still controversial. In this paper, we give evidence that non-superconducting YzBaCuO5 (211) inclusions can act as pinning centres in melt-
