## Abstract The ZnTi substituted barium hexaferrite polycrystalline samples have been synthesized by solid‐state reaction method. The complex permittivity and permeability measurements are carried out on the BaFe~12–2__x__~Zn~__x__~Ti~__x__~O~19~ (0.2 ≤ __x__ ≤ 0.6) samples in the microwave freque
In order to improve the margin for operating temperature changes and to achieve high recording performance, Co±Sn substituted Ba-ferrite particles were investigated. It was found that BaFe 12À2x Co x Sn x O 19 particles with x = 1.10 to 1.40 not only have a coercivity suitable for magnetic recording
