The invention discloses an organic nanomagnetic-core material mixed with inorganic particles coated with oleic acidfor transformers. The material comprises, by weight, 15-20 parts of ferrocenemonocarboxylic acid chloride, 6-11 parts of carbon black, an appropriate amount of 65% concentrated nitric acid, 80-100 parts of thionyl chloride, 72-86 parts of ethylene glycol, an appropriate amount ofdeionized water, an appropriate amount ofmethylene dichloride, 3-8 parts of ferrous sulfate, an appropriate amount ofammonium hydroxide, 19-24 parts of phenylamine, 10-20 parts of D-camphorsulfonic acid, an appropriate amount of N,N-dimethylformamide, 2-4 parts of ammonium persulfate, an appropriate amount ofabsolute ethyl alcohol, 1-3 parts of coupling agent of organic titanate, 2-6 parts of polyethylene, 2-4 parts of natural rutile, 0.4-1 parts of oleic acid, and 2-5 parts of diamond powder. According to the material, hydroxyl is introduced into the surface of the carbon black and reacted with ferrocenemonocarboxylic ac
