The suspension structure of magnetic ellipsoid nanoparticles is studied as they are driven by toggled magnetic fields in a microgravity environment. Suspensions coarsen in the applied field, but do not phase separate fully due to attraction induced by their remenant magnetism. The structure and kinetics of coarsening depend on the aspect ratio of the particles. The coarsening of ellipsoids with aspect ratio depends on the field strength and toggle frequency. Longer ellipsoids () form long fibrous structures that aggregate laterally with kinetics that are less sensitive to the field conditions. These results suggest an interplay between colloidal interactions, particle shape, and driving field that can be used to control the suspension microstructure.
