In this paper, we report the experimental observation of electro-optics effect in the ferrofluids comprising of Fe3O4 nanoparticles by a 1 mW He-Ne laser beam. An external electric field was applied perpendicular to the beam. Ferrite ferrofluid was prepared by using a coprecipitation-sonochemical technique. The effect of the electric field on the optical properties of ferrofluid was still too weak as we had expected. One possibility that can be suspected as the cause is that the electric field applied to ferrofluid is still too weak. © Published under licence by IOP Publishing Ltd.
