| Abstract: | Nanocrystalline ZnFe2O4 particles of several nanometers in size have been prepared by an improved coprecipitation method. Their particle structure, morphology and EPR properties were examined by XRD, TEM and EPR, respectively. It was found that ZnFe2O4 nanocrystalline could be produced at rather low temperature and was small. The EPR properties of the ZnFe2O4 nano powders were presented and discussed in terms of the observed temperature effect. |
