Abstract
Samples of NiFe2O4 nanoparticles N1 (nonactivated), N2 (milled for 15 min) and N3 (milled for 30 min) were studied using X-ray diffraction, scanning electron microscopy with energy dispersion spectroscopy, isothermal magnetization measurement and Mössbauer spectroscopy with respect to analyze the effect of particle milling on their magnetic properties. It was shown that an increase of the milling time lead to: (i) a decrease of particles’ size, (ii) a decrease of the saturation magnetic moment and (iii) an appearance of paramagnetic doublet in the Mössbauer spectra of NiFe2O4 nanoparticles.
