Two dimensional magnetic materials have received great attention since 2D magnets Cr₂Ge₂Te₆ and CrI₃ were first discovered at 2017, for they combine two-dimensional quantum properties, intrinsic magnetic order, and even topology together. Exploring the magnetic van de Waals family and controlling their physical properties by external field will accelerate the development of novel physics and the application of spintronics. Herein, I’ll first report the electric and magnetic properties of 2D magnetic Cr₂Ge₂Te₆ by transport measurement. Through gating, an insulator-metal transition and anomalous Hall effect are observed, which indicate intrinsic magnetism inside 2D Cr₂Ge₂Te₆ flakes. In addition, I’ll also describe our work in discovering a layered ferromagnetic compound MnSb_1.8Bi_0.2Te₄ by neutron scattering and transport properties, which is dissimilar to its parent materials MnBi₂Te₄ or MnSb₂Te₄ showing an anti-ferromagnetic ground state. At last, I am also pleased to share our recent attempts on exfoliating large area 2D quantum materials with a metal assisted method.
