We study the emergence of edge-magnetism in zigzag nanoribbons from electron-electron interactions in a minimal 3-band tight-binding descrip¬tion of transition-metal dichalcogenide monolayers with an intra-orbital Hub¬bard term. We explain the influence of each orbital in the magnetic ordering, comparing the results of Mean Field Theory and determinant Quantum Monte Carlo. We focus on a gapped edge-antiferromagnetic phase appearing at three-quarter edge-filling for realistic values of the interaction.
