Abstract
The synthesis of cobalt ferrites (CoxFe3-xO4) materials with sympathetic size and tunable magnetic properties is used for the promising industrial and biomedical applications. Such cobalt ferrites nanoparticles have been employed by co-precipitation technique. XRD analysis revealed that the average crystallite size of synthesized powder is 9 nm using (311) peaks, and it has exhibited polycrystalline structure. FTIR spectroscopy showed the formation of ferrite phase with high- and low-frequency bands at 573 cm−1 and 455 cm−1, respectively. The TEM images exposed that the materials have been well agglomerated along with spherical-shaped nanoparticles. EDX study confirmed the presence Co, O, Fe and C with stoichiometric composition and no more impurity detected in the spectrum. The VSM analysis revealed that the sample exhibits the hard magnetic materials. In addition, the magnetic anisotropy increases (19.05 → 344.84 erg/g) when Co is added with Fe3O4. EPR spectroscopy confirmed the ferromagnetic behavior of composites.
