Abstract:

This paper presents magnetic properties of manganese substituted barium hexaferrite BaFe_12-xMn_xO₁₉ single crystals. Crystals of BaFe_12–xMn_xO₁₉ with x up to 1.5 and sizes up to 8 mm were observed. The influence of Fe substitution by Mn on the magnetic properties was investigated. For the BaFe_10.5Mn_1.5O₁₉ single crystal samples saturation magnetization reduced from 72 to 63.5 emu/g at room temperature, and Curie temperature decreased from 455 to 380 °C.
