Fig. 1: Illustration of the unit cell and three boundary cuts for cb-AFM monolayer FeSe.

From: Fragile topological band in the checkerboard antiferromagnetic monolayer FeSe

Fig. 1

a The crystal and magnetic structure of monolayer FeSe. b Maximal symmetry Wyckoff positions in MSG \(P4^{\prime}\)/\(n^{\prime} m^{\prime} m\). Since monolayer FeSe is 2D, only the z = 0 Wyckoff positions are manifested. c, d Three distinct boundary cuts. Cut #1 represents the boundary of AFM edge. Cuts #2 and #3 represent the boundary of FM edge with spin-up and spin-down polarization along c-direction.
