We show that, at high spinning frequency, hydrodynamics dominate over attractive magnetic interactions and impede coarsening, forcing the particles to assemble into a collection of finite rotating clusters of controllable size. We introduce a minimal particle-based model that unveils the fundamental role of hydrodynamics and the boundary plane in the self-organization process of the colloidal spinners. Our results shed light on the control of coarsening and dynamic self-assembly in chiral active systems and the key role played by fluid mediated long-range interactions. cc-by (c) Massana-Cid, Helena et al., 2021 https://creativecommons.org/licenses/by/4.0/ info:eu-repo/semantics/openAccess Col·loides Quiralitat Ferromagnetisme Colloids Chirality Ferromagnetism Arrested phase separation in chiral fluids of colloidal spinners info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion
