Spin dynamics simulations of 2D magneic materials

2D magnetic materials have been studied intensively since their discovery in 2017. However, most of the studies focus on their static properties. We present our studies of spin dynamics simulations of 2D magnetic materials using the Heisenberg spin model with the spins on a honeycomb lattice. We compare our results with the spin wave spectra of chromium triiodide (CrI₃) obtained by neutron scattering experiments.
