| Abstract: | MnFe_2O_4 nanocrystals were prepared by low-temperature coprecipitation method,high temperature method and hydrothermal method respectively.And the samples obtained by the three methods were characterized by XRD,TEM and VSM.The preparation for MnFe_2O_4 nanocrystals using precursor with low-temperature coprecipitation method was studied in detail.Comparison and analysis of the three methods indicated that low-temperature coprecipitation method was optimal in the preparation of pure samples with small size. |
