Recent advancement in the bulk fabrication process has enabled the production of large single-grain bulk RE-Ba-Cu-O superconductors with high Jc values, which can trap fields much higher than those associated with conventional permanent magnets. However, a large electromagnetic force acts on the bulk superconductors when they trap a large field, which sometimes leads to fatal fracture. In this study, we measured mechanical properties of single-domain Y-Ba-Cu-O and Sm-Ba-Cu-O bulk superconductors from the output of strain gauges glued directly to the sample surface. The stress was applied to the samples by reducing the external fields from 10 to 0 T at 50 K. It was found that Ag addition is effective in improving the mechanical properties of melt processed Y-Ba-Cu-O and Sm-Ba-Cu-O.
