摘要
Static and dynamic magnetic properties are examined for granular systems Co-x(TiO2)(1-x) with Co volumetric contents of 31.6, 41.4, 49.4 and 57.6 vol%. The ferromagnetic resonance (FMR) technique in the 38-45 GHz band and the vibrating sample magnetometer technique were applied. The results from comparative analysis of saturation magnetization defined by both methods are discussed and the estimation of the most probable sizes and shapes. of magnetic particles forming the nanocomposite is carried out.
