The coprecipitated magnetite particles were coated by anionic surfactant, that is, polyoxyethylene alkyl ether acetates whose hydrophile-lipophile balance was about 6. The surfactant coated magnetite was washed by ethanol to remove excess amount of surfactant on magnetite surface. The washed magnetite particles were well dispersed in methyl phenyl polysiloxane. The saturation magnetization of concentrated silicone oil based magnetic fluid was approximately 0.05T. When the magnetic fluid was used in a cylindrical damper, the magnification factor at resonance point decreased and the frequency at resonance point depended on amplitude of damper.
