[13a-B406-7] Control of chemical composition and superconducting properties of Er247
Keywords:superconductivity
In this study, relationship between synthesis conditions and synthesis of Ca- and/or Sr-doped Er247 was investigated. For Er247 samples with almost single phase were successfully synthesized by sintering only for 3 h. Undoped Er247 samples showed improved Tc as decrease in sintering time, while Tc decreased by doping of Ca. (Ca,Sr) co-doping samples showed unchanged Tc.
