Fabrication of Ba-Hexaferrite Quasi-single Crystals and their Magnetic Properties
Source abstract
Abstract
Barium hexaferrite(BaFe12O19,BaM) with large uniaxial magneto-crystalline 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 nano-sized 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.
