In this study, relationship between synthesis conditions and synthesis of Ca- and/or Sr-doped Dy247 was investigated. For Dy247 samples with almost single phase were successfully synthesized by sintering only for 1 h. Undoped Dy247 samples showed improved T_c as decrease in sintering time, while T_c decreased by doping of Ca. (Ca,Sr) co-doping samples showed unchanged T_c. Post-annealing effects on superconducting properties of Er247 and Dy247 were also investigated in this study.
