| contents | We synthesize MoS$_{2}$ atomic layer flakes at different growth conditions to tailor S-terminated and Mo-terminated edge defect states that are investigated for their ferromagnetic response. We leverage quantum weak measurement principles to construct a spin Hall effect of light-based magneto-optic Kerr effect (SHEL-MOKE) setup to sense the ultra-small magnetic response from the synthesized atomic layers. Our findings demonstrate that Mo-terminated edge states are the primary source of ferromagnetic response from MoS$_{2}$ flakes, which is consistent with X-ray photoelectron, Raman and photoluminescence spectroscopic results. In the process, we demonstrate SHEL-MOKE to be a robust technique to investigate ultra weak properties in novel atomic-scale materials. |
