Multicomponent Magneto-Orbital Order and Magneto-Orbitons in Monolayer VCl.

Van der Waals monolayers featuring magnetic states provide fundamental building blocks for artificial quantum matter. Here, we establish the emergence of a multicomponent ground state featuring magneto-orbital excitations of the 3-transition metal trihalide VCl monolayer. We show that monolayer VCl realizes a ground state with simultaneous magnetic and orbital ordering by using density functional theory.
