Аннотация: Single-domain particles of SrFe₈Al₄O₁₉ were prepared by thermal treatment of porous products of citrate–nitrate autocombustion at 1200°C, and the effect of synthesis time on the particle morphology and magnetic properties was estimated. The procedure allows one to obtain SrFe₈Al₄O₁₉ particles with mean diameters of 100–460nm and coercivity ranges from 14.5 to 18.4kOe, while ferromagnetic resonance frequencies vary from 149 to 164GHz.

Ключевые слова: hexaferrites, ferrites, magnetic materials, permanent magnets, high coercivity, ferromagnetic resonance.
