Several growing modes including the bottom growth, the growth on a thermocouple ball and the top seeded growth, were tested to grow BaFe 12−2 x Mg x Ti x O 19 and BaFe 12− x Ga x O 19 magnetoplumbite single crystals from the Na 2 OBaO flux. Disadvantages of the bottom growth, inhomogeneities, inclusions, difficult separation of the crystals were restricted by using of the top‐seeded growth and by optimization of the ACRT program.
