Theoretical prediction of Curie temperature in two-dimensional ferromagnetic monolayer

Theoretical prediction of Curie temperature ( T C ) is vital importance for designing spintronic devices in two-dimensional (2D) ferromagnetic materials. Herein, based on the extensive investigation Monte Carlo simulations, we summarize and propose an improved method to estimate more precisely, which includes different contributions multiple near-neighbor interactions. Using monolayer CrI 3 as example, trends with biaxial strain are investigated via mean-field formulas, our method. Our not only accurate convenient predict 2D honeycomb lattice , but it can also be extended predicting other lattices. work paves way accelerate discovery novel ferromagnets applications.
