  • Equilibrium patterns of chain clusters composed of ferromagnetic particles in an external magnetic field, Tomofumi Ukai, Toru Maekawa, Hisao Morimoto, International Journal of Modern Physics B, 16,   2002年07月20日, We carry out Monte Carlo simulations of a ferromagnetic colloidal system, which is subjected to an external magnetic field, to investigate the structures formed by chain clusters. The control parameters are the ratio of the dipole moment energy to thermal energy, λ, and the ratio of the interactive energy between the dipole and the external magnetic field to thermal energy, ξ. We investigate the effect of the system height on the pattern formations for λ = 18 and ξ = 30, ∞. Note that the system becomes paramagnetic when ξ = ∞. We find that as the system height increases, chains coagulate to form fat clusters and spatially ordered structures are created when ξ = 30, whereas chains form thin meandering walls when ξ = ∞.
