Fe/Co molar ratio - Opis:
- Different grades of magnetic cobalt ferrite (Co_xFe_{3-x}O₄) nanoparticles were synthesized with various molar ratios of Fe²⁺ to Co²⁺ ions in the initial salt solutions method with using contact non-equilibrium plasma. The crystal structure and morphology of the nanoparticles are obtained from X-ray diffraction and transmission electron microscopy studies. With an increase in the value of x, the saturation magnetization for the samples of CoFe₂O₄ has decreased from 150.9 emu/g to 1.2 emu/g. The dependence of the coercive force on x is extremal with a plateau maximum corresponding to the x=0.5-1.25.
