By using top seeding melt-textured growth process, single domain GdBa ₂Cu₃O_7-δ bulk superconductor has been fabricated successfully in growth with the additions of two Nd ₂BaCuO₅ (Nd123) seeds. Both microstructure and superconducting properties were investigated from the seed position to the boundary of the sample. The experiments showed the enhanced superconducting properties such as the critical current density (J_c) and the irreversibility (B_irr) in the edge of the domain and the part between two seeds. The additions of two Nd123 seeds accumulate the richer Gd ₂BaCuO₅ inclusion particles and improve the J_c at the edge of single domain, which is confirmed by scanning electron microscopy.
