Magnetic colloids

Magnetic colloids or so-called magnetic fluids were studied from different points of view. In particular coupled Brownian motion of the magnetic moment and the particle was considered. These models are applied for the description of the viscosity change of colloids in an applied field, in the nuclear magnetic resonance relaxometry. Magnetic colloid in an external AC field is an example of the active medium. The transformation of the rotation of colloidal grains into the macroscopic motion is the particular example of this. Important issue is magnetization relaxation equations describing the supply of the electromagnetic energy to the mechanical motion of colloidal grains. These were studied by the Brownian dynamics. Phase transformations of magnetic liquids leading to their demixing were studied in the mean field approximation and the formation of modulated phases were described.
