Original Paper


Magnetic properties of nonmagnetic metal-doped SiC monolayer are studied by the first-principle methods. Different dopants (Al, Ga, Li, Mg, and Na) and doping sites are considered. Similar as transition metal (TM) atoms, magnetic behavior appears in Li-, Mg-, and Na-doped system. In addition, according to the calculated binding energies, the Mg-doped system is the most stable-formed system among the above three magnetic materials. Hence, we study the ferromagnetic interaction in two Mg-doped SiC monolayer. Interestingly, as the increasing Mg–Mg distance, the interaction between two Mg dopants prefers to a long-range FM coupling, which originates from a p-d exchange-like s-p coupling interaction.
