Abstract

Single-domain GdBa₂Cu₃O_7-δ (Gd123) bulk superconductors were fabricated in air and studied with different BaC ₂ contents and Gd₂BaCuO_7-δ (Gd211) initial particle sizes. The experiments showed that BaO₂ addition effectively suppressed the Gd/Ba substitution and therefore enhanced superconducting properties such as J_c and B_irr. An optimum addition amount is Gd123:BaO₂ = 1:0.1 molar. By employing fine Gd211, J_c at low magnetic fields is further enhanced. At B = 0 and 77 K, J_c reached 86 000 A cm^-2, which is a record high J_c value for melt-processed Gd123 bulk samples in air.
