Annotation Determination of particle size distribution of the magnetic colloids according to the static and dynamic light scattering and magnetic birefringence were produced. Shown that the magnetic colloids with a low concentration of the solid phase are characterized by steady bimodal distribution, including individual nanoparticles with a size of 10-20 nm and aggregates of particles with a size of 40-80 nm.
