By first-principles calculations, the magnetism of hole doped tin dichalcogenides SnX<sub>2</sub> (X = S, Se) monolayers is systematically studied. It is found that a phase transition from nonmagnetic to ferromagnetic ground state appears once above the critical hole density (~10<sup>14</sup> cm<sup>-2</sup>). The spin magnetic moment can maintain a magnitude of 1.0 μ<sub>B</sub>/hole with excellent stability of ferromagnetic state. Furthermore, we demonstrate that strain is very useful to modul ...[more]
