Abstract

Many-body interactions play an important role in self-assembly of colloidal particles in external rotating magnetic fields, which has not been sufficiently studied due to experimental difficulties. The study of the phase diagram and melting scenarios of colloidal particles with an effective interaction potential in an external rotating magnetic field has shown that not only the precession angle of the fields, but also the long-range radius of the three-body part of the potential has a decisive influence on the domain boundaries on the phase diagram, including gas-liquid critical and triple points.
