Using tight-binding models and first-principles calculations, we demonstratethe possibility to achieve a quantum anomalous Hall (QAH) phase on atwo-dimensional square lattice, which can be realized in monolayers of doubleperovskites. We show that effective intersite spin-orbit coupling between egorbitals can be induced perturbatively, giving rise to a QAH state. Moreover,the effective spin-orbit coupling can be enhanced by octahedral rotations.Based on first-principles calculations, we propose that this type of QAH statecould be realized in La2MnIrO6 monolayers, with the size of the gap as large as26 meV in the ideal case. We observe that the electronic structure is sensitiveto structural distortions, and that an enhanced Hubbard U tends to stabilizethe nontrivial gap.
