Microwave absorption of sintered M-type hexaferrites (BaFe 12−2 x Ru x Zn x O 19 ) is investigated as a function of the substitution ratio x . The substitution with Ru and Zn has been shown to reduce the axial anisotropy of the BaM-hexaferrite which becomes in-plane for x ≈ 0.4. Large saturation magnetization and in-plane magnetic anisotropy allow to obtain high permeability values at microwave frequencies. To study the behavior of the ferrites at these frequencies, the complex constitutive… CONTINUE READING
