In this study, Fe₃O₄ and CoFe₂O₄ magnetic nanostructures were successfully synthesized by a modified coprecipitation method with the participation of a natural stabilizer, and their structural, electronic, and magnetic properties were comprehensively studied. As a result of quantum-chemical calculations, the HOMO and LUMO energies for Fe₃O₄ were determined to be –5.84 eV and –3.27 eV, respectively, with an energy gap of 2.57 eV, while for CoFe₂O₄ these values were –5.61 eV, –2.74 eV, and 2.87 eV. In Hirshfeld surface analysis, the dnorm values for Fe₃O₄ ranged from –0.18 to +0.22 a.u. and for CoFe₂O₄, reaching +0.28 a.u., indicating strong interatomic interactions. EDS analysis confirmed the presence of Fe₂O₃ (80.8 mass%) and Co₂O₃ (19.1 mass%) in CoFe₂O₄. Intense peaks at 669 cm⁻¹ and 668 cm⁻¹, corresponding to Fe–O and Co–O bonds, were observed in the FTIR spectra. According to the VSM results, Ms = 72.4 emu/g, Mr = 14.8 emu/g, Hc = 185 Oe for Fe₃O₄, and Ms = 68.9 emu/g, Mr = 31.5 emu/g, and Hc = 1420 Oe for CoFe₂O₄ were determined. The obtained results showed that CoFe₂O₄ is a "hard magnetic" material with high magnetic anisotropy, and Fe₃O₄ is a "soft magnetic" material with high magnetic susceptibility, and confirmed that they are promising nanomaterials for adsorption, catalysis, and magnetic separation processes.
