Fig. 1: Schematic structure and spin configurations.

a Top and side view of MnPS3 monolayer and b the Mn atom honeycomb lattice and centering [P2S6] bipyramid. c Spin arrangements of the FM, Néel AFM, zigzag AFM, and stripy AFM, the purple and grey balls are the spin-up and spin-down state Mn atoms, respectively. The relative energies to the Néel AFM are presented as well.
