Abstract

We investigated processing, microstructure and superconducting properties of Gd123 single grain bulk superconductors with a large amount of BaCeO₃. The melt-textured bulk samples with compositions of Gd123 : BaCeO₃ : Gd211 = 100 : 40-x : x (x = 0-40) plus 20 wt.% of Ag₂O and 0.5 wt.% of Pt were fabricated in Ar-1%O₂ gas. The single grain bulk samples 25 and 33 mm in diameters were obtained with the composition of x = 5-40. It was observed that BaCeO₃ particles of 1-2 μm in diameters and Gd211 particles of 0.5-1 μm in diameters were dispersed in the melt-textured samples. Magnetic trapped fields of the 25 mm-sized samples with x = 10-40 were around 1 T at 77 K and the 33 mm-sized sample with x = 20 was 1.4 T at 77 K.
