| Abstract: Nano-MgFe2O4-Fe2O3 magnetic powders were synthesized by citrate gel under microwave irradiation. The structure，particle size distribution，electromagnetic characteristics of nano-MgFe2O4-Fe2O3 were characterized by using TG-DTA, X-ray, electronic microscope, nano-size measurement and electromagnetism measurement apparatus。The results show that the product is a mixture of MgFe2O4 and Fe2O3 with average size of 44 nm, tanδ for the product is 0.265 and 0.610 at frequency of 1.0 GHz and 1.8 GHz respectively. |
