Effects of Variations in Stoichiometry on M-Type Hexaferrites
Barium hexaferrite particles prepared by sol-gel technique yield best magnetic characteristics if a large barium surplus is used. Therefore, the powder sample has to be etched after the annealing process in order to get samples without intermediate phases. The used temperatures below 900°C and times shorter than 1h cause nanocrystalline hexaferrite particles with a specific saturation magnetization above 700 Acm2/g and a coercivity up to 470 kA/m
