Abstract

The capabilities of the small-angle neutron scattering (SANS) method for the research of various magnetic fluids with low magnetite concentrations (~0.1 vol.%), when the structural factor effect is absent, have been considered. The structural parameters of nanoparticles (the magnetic coherent scattering length density, thickness of a nonmagnetic layer on the surface of magnetic nanoparticles, and thickness of a stabilizing shell), which can be obtained from SANS experiments and the Guinier parameters for the scattering intensity, were analyzed in the framework of the “spherical core–shell” model. The model is found to be sensitive to a variation of the structural parameters of magnetic fluids if the particle polydispersity is taken into account. Experimental conditions for magnetite/oleic acid/benzene (a nonpolar carrier fluid) and magnetite/oleic and dodecyl-benzenesulphonic acids/pentanol (a polar carrier fluid) ferrofluids are selected and compared.
