Abstract
Magnetism in monolayer (ML) VSe<sub>2</sub> has attracted broad interest in spintronics, while existing reports have not reached consensus. Using element-specific X-ray magnetic circular dichroism, a magnetic transition in ML VSe<sub>2</sub> has been demonstrated at the contamination-free interface between Co and VSe<sub>2</sub>. Through interfacial hybridization with a Co atomic overlayer, a magnetic moment of about 0.4 μ<sub>B</sub> per V atom in ML VSe<sub>2</sub> is revealed, approaching values predicted by previous theoretical calculations. Promotion of the ferromagnetism in ML VSe<sub>2</sub> is accompanied by its antiferromagnetic coupling to Co and a reduction in the spin moment of Co. In comparison to the absence of this interface-induced ferromagnetism at the Fe/ML MoSe<sub>2</sub> interface, these findings at the Co/ML VSe<sub>2</sub> interface provide clear proof that the ML VSe<sub>2</sub>, initially with magnetic disorder, is on the verge of magnetic transition.
