Self-propelled particles can also be used to dynamically drive colloidal systems to nonequilibrium steady-states. We investigate colloidal systems that combine both of these methods of directed assembly, simulating mixtures of passive dipolar colloids and active soft spheres in an external magnetic field using Brownian dynamics in two dimensions. In these systems, the dipolar particles align in the direction of the external field but the active particles are unaffected by the field. The phase behaviors exhibited included percolated dipolar-network, dipolar string-fluid, isotropic fluid, and a phase-separated state. We find that the external field allows the dipolar particles to form a percolated network more easily compared to when no external field is present. Additionally, the mixture phase separates at lower active particle velocity in an external field than when no field is present. Our results suggest that combining multiple methods of directing colloidal assembly could lead to new pathways to fabricate reconfigurable materials.}, number={23}, journal={LANGMUIR}, author={Maloney, Ryan C. and Hall, Carol K.}, year={2020}, month={Jun}, pages={6378–6387} }
