Ferrite materials suitable for mm-wave circulators should exhibit ferromagnetic resonance (FMR) in the mm range with high a saturation magnetization. In addition, the magnetic and dielectric losses and the temperature dependence of the magnetocrystalline anisotropy and of the saturation magnetization should be as low as possible. Therefore, compositionally and microstructurally homogeneous materials are required. The object of the work presented was to investigate the microwave (MW) absorbing properties of nanocomposite bulk samples. As a filler we used magnetite (Fe3O4) with different particle sizes in a silicone rubber matrix and investigated the influence of the filler concentration and particle size in the polymer matrix on the MW nonlinearity in a large frequency range (1–20 GHz). We found that the intensity and the frequency at the reflection loss minimum depend on the particle size and particle concentration of magnetite in the samples.
