Abstract

We have investigated how the oxygen-annealing temperature and RE211 addition influence the flux creep at 77 K in melt-processed DyBa₂Cu₃O_7-δ (Dy123). By making conventional flux creep experiments, we found that Dy211 contents suppress the flux creep. It was also found that the flux creep is more suppressed by the annealing treatment in the lower temperature. A suppression in the flux creep was observed for samples with the secondary peak effect.
