Introduction
Models parameterized by first-principles calculations examine buckled honeycomb layers of group-V elements. They predict that in-plane magnetization can produce quantum anomalous Hall phases with absolute Chern number one or two, depending on spin–orbit coupling.
A closer reading
The in-plane orientation of the magnetization is central to the proposed design. Strain lowers the predicted threshold for some phases and supplies an experimental control parameter. A calculated gap is distinct from an observation of the effect at room temperature.
