Abstract

Cobalt ferrite (CoFe2O4) nanoparticle were obtained by different synthesis methods: coprecipitation (CO), ultrasonically assisted coprecipitation (US-CO), coprecipitation followed by mechanochemical treatment (MC-CO), microemulsion (ME) and microwave assisted hydrothermal synthesis (MW-HT). The structure and cation distribution are investigated by XRD diffraction analysis and Raman spectroscopy. The parameters such as chemical shift, quadruple splitting and hyperfine field and site occupancy of Fe3+ were determined by Mössbauer spectroscopy. The 57Fe-Mössbauer spectrа of the CoFe2O4 wеrе measured at room temperature in ± 12 mm s-1 Doppler velocity range. The 57Fe-Mössbauerspectrа of the CoFe2O4 samples wеrе fitted with the extended Voigt-based fitting method.
