Non\u2010collinear antiferromagnetic (\n                    <jats:italic>nc<\/jats:italic>\n                    AFM) state, characterized by spins lacking a specific orientation, remains enigmatic. Through first\u2010principles calculations and Wannier simulations, we predicted that the AB\u2010stacked CoBi\n                    <jats:sub>2<\/jats:sub>\n                    Te\n                    <jats:sub>4<\/jats:sub>\n                    two\u2010septuple layer (2SL) hosts an intrinsically intralayer\n                    <jats:italic>nc<\/jats:italic>\n                    AFM state while preserving a band inversion between Bi\u2010\n                    <jats:italic>p<\/jats:italic>\n                    and Te\u2010\n                    <jats:italic>p<\/jats:italic>\n                    orbitals in its bulk band structure. Intriguingly, we identified a group of flat bands near the Fermi level in the edge state of (210) nanoribbon terminated by\n                    <jats:italic>nc<\/jats:italic>\n                    AFM coupling.

This suggests that the formation of flat bands arises from the interplay between spin\u2010orbit coupling\u2013induced band inversion and the spatially varying local exchange field generated by intralayer\n                    <jats:italic>nc<\/jats:italic>\n                    AFM ordering.
