“…Substitution of transition-metal (TM) atoms is an efficient way to induce magnetism in nonmagnetic nanomaterials and has been confirmed both in experiments 17,18 and in theories. [19][20][21] For example, in theories, the substituted V, Cr, Mn, Co, Cu, and Zn atoms in graphene are stable, and give rise to a remarkable magnetic moment; 22 in the MoS 2 sheet, Mn, Fe, Co, Ni, Cu, and Zn impurity can induce magnetism and the magnetism strength can be effectively manipulated by the applied elastic strain. 21 In experiments, one of the most typical examples is the realization of the Kondo effect in graphene induced by magnetic impurities.…”
