Intrinsic ferromagnetism and the quantum anomalous Hall effect in two-dimensional MnOCl monolayers.

Due to their potential application in spintronic devices, two-dimensional (2D) ferromagnetic materials are highly desired. We used first-principles calculations and Monte Carlo simulations to investigate the electronic structure and magnetic characteristics of the MnOCl monolayers. We discovered two stable monolayer structures, -MnOCl and -MnOCl.
