Abstract
Magnetic properties of ReS2 monolayer doped with nonmagnetic metals (Ag, Al, Li, Mg, and Na) are studied by the first-principle method Different dopants and doping sites are considered. Similar to transition metal (TM) atoms, magnetic behavior appears in Al and Mg-doped systems. On the other hand, the calculated binding energies show that the Al-doped system has a more stable-formed system than the Mg-doped system. Hence, we study the ferromagnetic interaction in two Al-doped ReS2 monolayers. Interestingly, as the Al–Al distance increases, both ferromagnetic (FM) and nonmagnetic (NM) states are found. Our results deem that the FM coupling originates from a p-d exchange-like p-p coupling interaction.
