Faraday rotation in ligand capped Fe3O4 nanoparticles – Experimental investigations for single scattering model

•Faraday rotation data is reported in oleic acid and oleyl amine capped Fe3O4 nanoparticles prepared using wet chemical method.•Faraday rotation data is found to be independent of the concentration of the nanoparticles and the rotation saturates at moderate magnetic fields.•Faraday rotation data fits to a single scattering model compared to the well-known chain model.
