Single phase magnesium ferrites (MgFe2O4) were obtained by two different procedures. The observation by TEM suggested that the two samples were with particle sizes below 20.0nm. The results of Moessbauer spectra taken at 298K subsequently re vealed the completely or partially superparamagnetic natures of the two samples for their fine particle volume. Far-IR results first demonstrated the presence of double-splitting of V2 band for MgFe2O4. The difference of structural features between the two samples was found by ESR analyses. The reason was discussed.
- Ultrafine particle,
- MgFe₂O₄,
- ESR,
- IR,
- Moessbauer spectra
