Abstract The directional solidification and the interface structure of BaTiO3-CoFe2O4 eutectic grown by the floating zone melting method were investigated. The microstructure of the eutectic were found to consist grains of lamellar or fibrous morphology. Two types of crystal structures of BaTiO3 were observed for different growth conditions. The orientation relationships between BaTiO3 and CoFe2O4 (the spinel-type crystal structure) are a) hcp BaTiO3: (111) CoFe2O4 // (001) BaTiO3 and (110) CoFe2O4 // (110) BaTiO3, and b) tetra/cubic BaTiO3: (001) CoFe2O4 // (001) BaTiO3 and (100) CoFe2O4 // (100) BaTiO3. The interface has misfit dislocations due to the accommodation of lattice mismatch.
