Researchers at MIT and collaborators have demonstrated that they can alter the magnetic properties of chromium trichloride – an ultra-thin material that features a honeycomb-shaped atomic structure — by shifting the stacking order of layers. The researchers peeled away two-dimensional (2-D) layers of chromium trichloride using and found that the magnetism is different in 2-D and 3-D crystals, due to different stacking arrangements between atoms in adjacent layers.
