Ферромагнитный резонанс суперпарамагнитных композитов Fe2O3/SiO2
γ-Fe2O3/SiO2 powders with an average particle size of 10 nm were studied using ferro- magnetic resonance (FMR). The frequency and temperature dependences of the FMR parameters were analyzed within the framework of the anisotropic superparamagnet model. Saturation magnetization M = 300 G, magnetic anisotropy constant K ≈ 1.8·105 erg/cm3, and exchange surface anisotropy con- stant Ku ≈ 1.2·102 erg/cm2 were determined for the prepared powders
