This experiment was adopted by sol-gel,nitric acid,nitric acid manganese and iron teos,ethanol,deionized water as raw material to process,the preparation of manganese ferrite in spin coating method,and then get manganese ferrite thin sintering get to sample。Preparation of manganese ferrite sol,high temperature,high will not generate a violent reaction and black consoliated cost。Need to teos drops to keep stirring salt solution,which fully mixing。Got sol should pay attention to adjusting the PH value,make its PH in 2-3。Sol,should put day。ChenBy XRD,sem and magnetic properties of analysis,is helpful to MnFe2O4 / SiO2 composite membrane structure understanding,the correct understanding to the magnetic particles scattered on the structure of the mechanism of silica matrix。Magnetic particle dispersion and stable lies in the structure of silica matrix showed very dependent on the magnetic particle size,showing the characteristics of high magnetic permeability,high strength,low saturation magnetization coercive force and low loss characteristics。Keywords:sol-gel,magnetic conductivity,saturation magnetization strength,coercive force
