▎ 摘  要

Graphene-like quantum dots (GQDs) doped with magnetic ions are described in accordance with the mixed Ising model. The magnetic properties of this system are discussed within the frame-work of the effective field theory with correlations. The numerical results produced several types of phase diagrams with different exchange couplings and anisotropies. Certain unique features, such as reentrant phenomena, were found within a particular range of parameters. We concluded that GQDs doped with magnetic ions have the potential to adjust their performance and effectively enlarge the scope of application.
