- 論文の詳細を見る
Ternary Ba–Fe–As system has been studied to determine a primary solidification field of the BaFe2As2 phase. We found that the BaFe2As2 phase most likely melts congruently and primarily solidifies either in the FeAs excess or BaxAs100-x excess liquid. Knowing the primary solidification field, we have performed the vertical Bridgman growth using the starting liquid composition of Ba15Fe42.5As42.5. Large single crystals of the typical size $10\times 4\times 2$ mm3 were obtained and their quality was confirmed by X-ray Laue and neutron diffraction.
