We build a microscopic model to study the intralayer and interlayer superexchange due to
electrons hop** in chromium trihalides (Cr X 3, X= Cl, Br, and I). In evaluating the …

We derive the microscopic spin Hamiltonian for rhombohedral CrI 3 using extensive first-
principles density functional theory calculations that incorporate spin-orbit coupling and …
