Abstract EN
We present a study of magnetic and structural properties of CoFe2O4 nanoparticles suspended in an organic liquid.
Transmission electron microscopy shows that the nanoparticles have a narrow size distribution of average particle size 5.9 ± 1.0 nm.
X-ray diffraction shows that the particles are of cubic spinel crystal structure.
Dynamic light scattering measurements reveal the existence of an organic shell around the CoFe2O4 nanoparticles with an average hydrodynamic diameter of 14.4 nm.
Coercive magnetic field at T=5 K is found to be 11.8 kOe.
Disappearance of the coercive field and remanent magnetization at about 170 K suggests that the CoFe2O4 nanoparticles are superparamagnetic at higher temperatures which is confirmed by the room temperature Mössbauer spectrum analysis.
Saturation magnetization of the nanoparticles of 80.8 emu/g(CoFe2O4) at 5 K reaches the value detected in the bulk material and remains very high also at room temperature.
The cobalt ferrite nanoparticle system synthesized in this work exhibits magnetic properties which are very suitable for various biomedical applications.
