抜粋

Bulk (Sm0.5Eu0.5)Ba2Cu3O 7-δ superconductors were grown isothermally and with a vertical thermal gradient of -5°C/cm in air. The crystals grown at a large growth rate under the thermal gradient exhibited a high-Tc value of 95 K and a plateau in the Jc-B curve at 1-4 T at 77 K with postannealing in Ar. We found that the substitution of Ba by rare-earth (RE) elements could be suppressed with a large growth rate. The narrow range of RE-Ba solid solution was attributed to the fast crystallization rate of RE1+xBa2-xCu3O7-δ with low-x values.
