Two-Dimensional Monte Carlo Simulations to Capture Thick Chainlike Clusters of Ferromagnetic Particles in Colloidal Dispersions

摘要: The present study theoretically investigates the aggregate structures of thick chainlike clusters arising in ferromagnetic colloidal dispersions by means cluster-moving Monte Carlo method. Pair correlation functions are also evaluated to clarify internal themselves such clusters. following aggregation image has been obtained from simulations for a two-dimensional model system. Particles form when magnetic attractions between particles become strong over certain value. Such thin prefer nearly linear formation along field direction, if strength is sufficiently large. In this situation, attractive forces come act these clusters, and increase with lengths lead
