Abstract:

The nanocrystalline NiFe2O4 particles prepared by solution combustion synthesis technique using different fuels such as ethylene-diamine-tetra-acetic acid (NA sample) and urea (NB sample) were studied using magnetic measurement and Fe-57 Mossbauer spectroscopy with a high velocity resolution. The temperature dependence of magnetization is different for the two samples. Mossbauer spectra demonstrate the necessity to use more than two magnetic sextets, usually used to fit the NiFe2O4 nanoparticles spectra. Evaluation of the different local microenvironments for Fe in both tetrahedral (A) and octahedral (B) sites, caused by different Ni2 + occupation of octahedral sites, demonstrates at least five different local microenvironments for both A and B sites. Therefore, the Mossbauer spectra were fitted by using ten magnetic sextets which are related to the spread Fe-57 location in octahedral and tetrahedral sites.
