Abstract:
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.
Keywords:
