摘要 Mossbauer spectra for 5 nm Fe3O4 particles coated with different surfactants (the polar end groups as -COONa and -SO3Na) were measured and show a significant influence on superparamagnetic relaxation with and without the solvent. Some phenomena were explained by the superparamagnetism and the surfactant hydrophilicity.
