Fig. 1

The CrCl3−xyBrxIy alloys with a honeycomb-layered structure were synthesized by a CVT process from mixtures of CrCl3, CrBr3, and CrI3 in appropriate ratios. The gray, blue, green, and red spheres represent Cr3+, Cl, Br, and I, respectively. Cr3+ is a spin 3/2 ion with three electrons in the t2g manifold.
