Structure and static and dynamic magnetic properties of Sr[Fe.sub.12-2x][O.sub.19] hexaferrites produced by self-propagating high-temperature synthesis

A resource-effective process to synthesize Sr([Co.sub.x][Ti.sub.x])[Fe.sub.12-2x][O.sub.19] hexaferrites is proposed. The values of saturation magnetization and anisotropy field of the resulting materials are determined. It is shown that an interpretation of the ferromagnetic resonance (FMR) spectra...

Zusammenfassung:A resource-effective process to synthesize Sr([Co.sub.x][Ti.sub.x])[Fe.sub.12-2x][O.sub.19] hexaferrites is proposed. The values of saturation magnetization and anisotropy field of the resulting materials are determined. It is shown that an interpretation of the ferromagnetic resonance (FMR) spectra requires that anisotropy of the magnetomechanical ratio should be taken into account in addition to magnetic anisotropy. Keywords: SHS, hexaferrites, ferromagnetic resonance, crystallographic magnetic anisotropy.
