Physical origin of giant excitonic and magneto-optical responses in two-dimensional ferromagnetic insulators

The magneto-optical (MO) effects probe the electronic and magnetic properties of a material, particularly useful for 2D magnets. Here, the authors show that the large optical and MO responses in ferromagnetic monolayer CrI3 arise from strongly bound excitons, extending over several atoms.
