In this research the synthesis of [Co(Salen)(PPh3)(H2O)]4[Fe(CN)6] and [Co(Salophen)(PPh3)(H2O)]4[Fe(CN)6] schiff base complexes was reported. Co3O4/CoFe2O4 magnetic nanoparticles were prepared by calcination of these complexes at 500, 550 and 600°C. Precursor complexes were identified by FT-IR and UV-Vis spectroscopy and their thermal behavior was studied via TG/DTA. Nanomagnetic samples were characterized by X-ray diffraction (XRD), Scanning Electron Microscopy (SEM), and Fourier Transform Infrared Spectroscopy (FT-IR). Magnetic properties of the synthesized nanoparticles were studied using Vibrating Sample Magnetometer (VSM). Magnetic parameters such as saturation magnetization (Ms), remanent magnetization (Mr), coercive field (Hc) and squareness ratio (SQ = Mr/Ms) were determined at room temperature. Stoichiometry and approximate composition of the prepared samples were studied by Electron Diffraction X-ray spectroscopy (EDX). The prepared nanocomposites could be useful in some practical applications due to their high magnetization, good chemical stability and dispersion.
