Abstract

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 BaxAs 100-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 × 4 × 2 mm3 were obtained and their quality was confirmed by X-ray Laue and neutron diffraction.
