Abstract
We have succeeded in synthesizing RE-Ba-Cu-O (RE = Gd and Dy) bulk superconductors with excellent field trapping properties. Large c-axis oriented single-domain Gd-Ba-Cu-O bulk samples with Ag addition were melt-textured under controlled oxygen partial pressure of 1.0%. The Gd-Ba-Cu-O sample 50 mm in diameter could trap a high flux density of 2.4 T at 77 K. In addition, we measured the trapped field between two Gd-bulks in order to minimize the demagnetizing effect and found that it reached 3.3 T. The single-domain Dy-Ba-Cu-O/Ag bulk 48 mm in diameter was also fabricated in air and its trapped field was 1.9 T at 77 K.
