Here we explore the domain of formation of the MgCu2 structure as the softness and the reach of the attractive potential are increased. We show that the domain of existence of this Laves phase grows significantly for softer potentials. Experimentally, a softer potential could be achieved by using a longer polymer brush to coat the particles, starting from microgels, or simply by reducing the size of the hard cores. We will finally discuss the photonic band structure and the gap properties of the formed sublattices.
