Abstract

Static and dynamic magnetic properties of SHS-produced BaFe12–2x(CoхTiх)O19 (х = 1.0, 1.1, 1.2) and SrFe12–2y(CoyTiy)O19 (0 ≤ y ≤ 1.0) hexaferrites were characterized by magnetization and FMR measurements. Dynamic properties of SrFe12–2y(CoyTiy)O19 hexaferrites were rationalized in terms of not only magnetic anisotropy but also the anisotropy of magnetomechanical ratio. SHS-produced ferrites can be recommended for designing radar-absorbent coatings and other SHF devices operating in the range 20–50 GHz.
