Abstract

We study via molecular dynamics simulations the self-assembled structures formed by supracolloidal magnetic polymers (SMPs). These are small aggregates of magnetic colloidal particles with polymer-like structures that have been permanently stabilized by means of polymer crosslinking. Here we focus on the fundamental structural and magnetic properties of the self-assembled motifs formed by pairs of identical SMPs under different conditions. We observe that the minimum characteristic density at which the self-assembly of both SMPs into a single aggregate becomes dominant is signaled by a maximum in their net magnetization and radius of gyration.
