Scandium-doped M-type barium hexagonal ferrites of the composition BaFe 12−x Sc x O 19 are well suited for low frequency microwave device applications such as isolators and circulators. A series of Sc-doped M-type barium hexagonal ferrite powders ͑x =0-1.2͒ were prepared by conventional ceramic processing techniques. The resulting powders were verified to be pure phase and maintain the nominal chemical stoichiometry by x-ray diffraction and energy dispersive x-ray spectroscopy, respectively.doi:10.1063/1.2838232 fatcat:n5siiwioabcfvitbetfjgd3vwq
