%X Barium hexaferrite (BaFe12O19, BaM) with large uniaxial magnetoa2crystalline anisotropy is a key gyromagnetic material for the millimeter wave device. BaM quasi-single crystal materials with a grain orientation degree(GOD) of 99% were successfully fabricated by using nanoa2sized single-domain BaM crystallites as the starting materials via press-forming in magnetic filed and sintering with minor liquid participation. The as-fabricated BaM quasi-single crystals were characterized with the saturation magnetization of 4654kA/m, the coercity field of 9.552kA/m and their formation mechanism was also discussed.
