Abstract
YBaCuO prepared by the Melt-Powder-Melt-Growth (MPMG) process has a high critical current density. It has been found that non-superconducting Y2BaCuO5 (211) particles dispersed in the 123 superconducting phase work as pinning centers, resulting in high Jc values. The direct summation model predicts that the critical current density is proportional to the ratio of the volume fraction of non-superconducting particles to the size of those particles. The measured values of the critical current density increased with increasing volume fraction of the 211 particles and decreasing size of those particles. Therefore, the critical current density is proportional to the ratio of the volume fraction of the 211 particles to the size of those particles, which is in good agreement with the model.
