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

Abstract The moiré engineering of two-dimensional magnets opens unprecedented opportunities to design novel magnetic states with promises for spintronic device applications. possibility stabilizing skyrmions in these materials without chiral spin-orbit couplings or dipolar interactions is yet be explored. Here, we investigate the formation and control ground state topological spin textures (TSTs) $${Cr}{I}_{3}$$ C r I 3 using stochastic Landau–Lifshitz–Gilbert simulations. We unveil emergence interlayer vortex antivortex Heisenberg exchange fields, spontaneous field-assisted TSTs various topologies. developed study accounts full bilayer dynamics, thermal fluctuations, intrinsic couplings. By examining effect Kitaev interaction next nearest-neighbor Dzyaloshinskii–Moriya interaction, propose latter as unique coupling mechanism compatible experiments on monolayer twisted . Our findings contribute current knowledge about skyrmionics uncover nature
