Moiré Skyrmions and Chiral Magnetic Phases in Twisted CrX<sub>3</sub> (X = I, Br, and Cl) Bilayers
We present a comprehensive theory of the magnetic phases in twisted bilayer Cr-trihalides through a combination of first-principles calculations and atomistic simulations. We show that the stacking-dependent interlayer exchange leads to an effective moir\'e field that is mostly ferromagnetic with antiferromagnetic patches. A wide range of noncollinear magnetic phases can …
