Two-dimensional ferromagnetism in few-layer van der Waals crystals: Renormalized spin-wave theory and calculations
TL;DR: In this paper, a renormalized spin-wave theory was used to study the ferromagnetic behavior in Heisenberg-type 2D ferromagnets, and applied to few-layer Cr2Ge2Te6 crystals.

Physical origin of giant excitonic and magneto-optical responses in two-dimensional ferromagnetic insulators
TL;DR: The authors show that the large optical and MO responses in ferromagnetic monolayer CrI3 arise from strongly bound excitons, extending over several atoms, providing physical understanding of the phenomena as well as potential design principles for engineering magneto-optical and optoelectronic devices using two-dimensional magnets.
