We perform computer simulations of a non-Brownian suspension of paramagnetic particles sedimented onto a substrate and subjected to a rotating magnetic field. We vary the dimensionless rotation rate, Mason number(Mn), and find a metastable active rotating chain(ARC) phase where particles organize into chains which extend along the axis of the field and rotate with the field. The length of the chains decays monotonically with increasing Mn until it reaches the particle scale. The ARC phase is metastable, and we observe the nucleation of crystalline clusters which, unlike the chains, do not rotate with the field. We monitor the time it takes for a given fraction of the particles to leave the ARC phase to join the crystalline phase, and we find the lifetime of the ARC phase has a non-monotonic dependence on Mn. It is longest-lived at Mn*(approximately at 0.2). The crystal nuclei which form are qualitatively different above and below Mn*. Below Mn* relatively few nuclei form and grow with time, while above Mn* many small nuclei form and do not evolve significantly over the lifetime of our simulations. We show that the terminal size of the clusters after growth is controlled by the length of the chains in the ARC phase. Our results should have important technological implications both for applications which seek to exploit mechanical properties of the ARC phase such as rheological actuators and for applications which seek to employ magnetic fields to control assembly of particles.
