dcterms:description
Nanosize NiFe2O4 was synthesized via precipitation process in which soluble starch is used as dispersing agent and Na2CO3 as precipitation agent. NiS04 was used as precursor for NiO, and Fe(NO3)3 as precursor for Fe2O3. Considering that the magnetic properties of nanocrystalline NiFe2O4 ferrites are directly related to their structure and phase composition, obtained reaction products were analysed and discussed through structural, compositional and magnetic characterisation. Formation of pure nanosized NiFe2O4 phase has been confirmed by the subsequent X-ray diffraction analysis (XRD), Fourier transform infrared spectroscopy (FTIR) and 57Fe Mössbauer phase (MS) analyses. Average crystalline size of 21 nm was determined by XRD and material’s nanocrystalline structure was additionally supported by results of field-emission and conventional scanning electron microscopy FE-SEM/SEM. The obtained room temperature magnetic hysteresis loop, measured on vibrating sample magnetometer (VSM), exhibits characteristic “S shape with values of magnetic properties within expected range for this material.
