Whirling interlayer fields as a source of stable topological order in moiré CrI3

Abstract

The reduced dimensions of 2D magnets expose their magnetic anisotropy, adding a twist into the system provides another degree of freedom to explore. Here, the authors use stochastic Landau–Lifshitz-Gilbert simulations to investigate ground-state topological spin textures induced by interlayer fields in twisted bilayer CrI3.
