MMC effective magnetic moment dependence on the field induction square for several types of constituent nanoparticles: particle rotation in the liquid and interaction with the external field (filled diamonds), particle rotation in the liquid, interaction with the external field and lognormal size distribution of the MMCs (filled squares: D_m = 12 nm and σ = 1 nm, filled triangles: D_m = 12 nm and σ = 3 nm), particle rotation in the liquid, interaction with the external field and dipole-dipole interactions between the MMCs (open diamonds), and particle rotation in the liquid, interaction with the external field, log-normal size distribution of the MMCs and , interaction with the external field and dipole-dipole interactions between the MMCs (open squares: D_m = 12 nm and σ = 1 nm, open triangles: D_m = 12 nm and σ = 3 nm).
