摘要：
We investigated the effect of Ag2O addition on the microstructures, the superconducting properties, the field-trapping capabilities and the mechanical properties of Nd-Ba-Cu-O (Nd123:Nd422 = 10:2) bulk superconductors. The samples were added with 10 wt% and 20 wt% Ag2O and grown in 1% O-2-Ar atmosphere. The superconducting properties and the field-trapping capabilities were not affected by AgO content; however, the mechanical properties were greatly Improved with increasing Ag2O content. The sample with 20 wt% Ag2O exhibited the Weibull coefficient exceeding 13.
