Study of Specific Features of Laser Radiation Scattering by Aggregates of Nanoparticles in Ferrofluids Used for Optoelectronic Communication Systems

Ferromagnetic fluids are considered to be advanced materials both for the fundamental research and for possible applications, among which some integrated optic devices with the elements containing ferrofluids and controlled by an external magnetic field have recently been discussed. This work is devoted to the experimental study of the factors affecting the intensity and spatial distribution of the laser radiation scattered by the particle structures in ferrofluids in a zero magnetic field and in the presence of magnetic field with H = 1000 Oe. The samples of nanodispersed magnetite (Fe3O4) suspended in kerosene and in water were studied. Certain trends determining the scattering patterns were observed.
