In ferronematics, a uniform field, acting on magnetically hard ferroparticles, causes the particles to rotate. This change in orientation, owing to the collective behavior of the system, is transferred to the entire volume of the liquid crystal. This paper shows how a change in concentration in a uniform magnetic field leads to a change in stratification--an effect specific to ferronematics--and gives rise to conditions when a heavy impurity (ferroparticle) rises and is held stable above a layer of liquid with a lower density. Concentration profiles and orientational distributions formed in a twist cell under the simultaneous action of gravitational and segregational effects are studied and curves of equilibrium magnetization are constructed.
