The goal of this work is to justify a possibility to obtain and observe coherent spin relaxation—the superradiation (SR) effect—in molecular nanomagnetic structures. We note that giant-spin molecules have the magnetic moments of the order of and possess substantial magnetic anisotropy. Moreover, to invoke SR, such a system should be polarized to a high extent. When put together, these factors rule out the conventional treatment used e.g. for optical SR, and invoke development of novel approaches.
