Moiré-driven multiferroic order in twisted CrCl<sub>3</sub>, CrBr<sub>3</sub> and CrI<sub>3</sub> bilayers
Moiré-driven multiferroic order in twisted CrCl<sub>3</sub>, CrBr<sub>3</sub> and CrI<sub>3</sub> bilayers
Layered van der Waals materials have risen as a powerful platform to engineer artificial competing states of matter. Here we show the emergence of multiferroic order in twisted chromium trihalide bilayers, an order fully driven by the moir\'e pattern and absent in aligned multilayers. Using a combination of spin models …
