We have melt-grown the Nd-Ba-Cu-O superconductor from the precursor with a composition of NdBa2Cu3O(y) + 10% Nd4Ba2Cu2O10 + 0.5 wt% Pt + 1.0 wt% CeO2 in 0.1% O2-Ar environment. A combined addition of Pt and CeO2 has resulted in the refinement of Nd4Ba2Cu2O10 (Nd422) particles down to submicron size as revealed by optical and transmission electron microscopic observations. A large enhancement of critical current density reaching 105 A cm-2 in a self field at 77 K has been accomplished as a result of fine dispersion of Nd422.
