We fabricated bulk GdBa₂Cu₃O_7-δ (Gd123) superconductors with additions of Gd₂BaCuO₅ (Gd211) and Gd₂Ba₄CuMoO_x (Gd2411). We analyzed the relation between the addition amounts of Gd211/Gd2411 particles and critical current J_c. We found Gd2411/Gd211 particles formed a band structure which resulted in the inhomogeneous distribution of J_c in the Gd123 bulks. Gd2411 particles can stably exist in the vicinity of the seed site compared to Gd211 that is easy pushed out to edge area of single domain. This enhanced the critical current J_c in the vicinity area of bulks.
