Abstract

We fabricated bulk GdBa2Cu3O7-δ (Gd123) superconductors with additions of Gd2BaCuO5 (Gd211) and Gd2Ba4CuMoOx (Gd2411). We analyzed the relation between the addition amounts of Gd211/Gd2411 particles and critical current Jc. We found Gd2411/Gd211 particles formed a band structure which resulted in the inhomogeneous distribution of Jc 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 Jc in the vicinity area of bulks.
