Ligand-field helical luminescence in a 2D ferromagnetic insulatorLigand-field helical luminescence in a 2D ferromagnetic insulator, Published online: 04 December 2017; doi:10.1038/s41567-017-0006-7Atomically thin chromium tri-iodide is shown to be a 2D ferromagnetic insulator with an optical response dominated by ligand-field transitions, emitting circularly polarized photoluminescence with a helicity determined by the magnetization direction.
