| 英文摘要 | Polycrystalline CoFe2O4/NiFe2O4 powders were prepared by auto-combustion method using a novel amino-based gel. The thermal evolution of gel precursors, as well as the microstructure, morphology and magnetic properties of as-synthesized powders were studied in detail. Energy dispersive x-ray spectroscopy indicated that the ratios of Ni:Fe was close to the theoretical value (Ni:Fe = 1: 2), suggesting high purity of synthesized NiFe2O4 powders. The saturated magnetization (M-s) and residual magnetization (Mr) of CoFe2O4 were highly dependent upon the annealed temperatures. The Ms increased from 77.5 to 84.7 emu g(-1), and Mr increased from 37.7 emu g(-1) to 42.5 emu g(-1) by annealing from room temperature to 600 degrees C. The Ms of NiFe2O4 was 38.7 emu g(-1), much lower than that of CoFe2O4. The experimental results indicated that this auto-combustion method using amino-based gel was a suitable method for synthesizing high-quality CoFe2O4/NiFe2O4 powders. |
