抜粋

The field-trapping characteristics of recently developed Gd-Ba-Cu-O bulk superconductors will be reported. Large Gd-Ba-Cu-O bulk superconductors with Ag addition were melt-textured under controlled oxygen partial pressure of 1.0%. The single domain Gd-Ba-Cu-O bulk samples 24-50 mm in diameter with submicron-sized Gd₂BaCuO₅ inclusions could be fabricated without cracks. The field trapping abilities of the bulk samples could dramatically be enhanced through the size reduction of Gd₂BaCuO₅ particles and the enlargement of grain size. The trapped magnetic field of the bulk Gd-Ba-Cu-O superconductor 50 mm in diameter and 30 mm in thickness reached an extremely high value of 2.7 T at 77 K.
