395Modulating the magnetic properties of MoS(2) monolayers by group VIII doping and vacancy engineering“…The calculated results show that the magnetic properties of monolayer MoS(2) can be tuned by changing the distribution of the G8 atom and S vacancy. The S vacancy tends to decrease the net magnetic moment of the doped system when these two defects are in their closest configuration. …”
