Abstract

The authors tried to produce high critical current density (J_c) bulk superconducting material by a melt process. It became clear that the grain boundary region acts as a weak-link and causes the low J_c of the sintered material. It was found that highly oriented bulk material can be produced by a melt process in YBaCuO system. The authors obtained samples which contained many fine Y₂BaCuO₅ (211) phases and no grain boundary throughout a region of several tens of cubic millimeters. By magnetization measurements, it was found that J_c exceeded 10⁴ A/cm₂ at 77 K and 1 T, which is a promising value for practical applications.
