Abstract
We have succeeded in synthesizing a powder form of Gd 2Ba 4CuFeO y (Gd2411) in air. GdBa 2Cu 3O 7− δ (Gd123)/Gd 2BaCuO 5 (Gd211) precursor powders added with different amounts of Gd 2Ba 4CuFeO y ( x = 0, 0.002, 0.004, 0.02) in molar ratio to Gd123 have been fabricated successfully into the form of large, single grains by the top seeded melt growth (TSMG) process. The relation between the additions amounts of Gd2411/Gd211 and critical current density ( J C) was analyzed. We found Gd2411 particles stably exist in the Gd123 matrix without degradation of superconducting properties owing to the existence of the Fe magnetic ion. The trapped field was observed to increase significantly compared with the bulk without Gd2411 additions.
