Abstract

Controlling the magnetic and electronic properties of 2D materials is important for their promising applications in low-dimensional spintronics. In this paper, the authors are focused on the control and manipulation of spin-spin interactions in monolayer CrI${}_{3}$ by applying strain and electric fields. A suitable spin model Hamiltonian is used to compute the isotropic and anisotropic symmetric exchange interactions, Dzyaloshinskii-Moriya interactions, and anisotropy energy of monolayer CrI${}_{3}$ as a representative of 2D transition metal trihalides.
