Chern and Z(2) topological insulating phases in perovskite-derived 4d and 5d oxide buckled honeycomb lattices
Based on density functional theory calculations including a Coulomb repulsion parameter U, we explore the topological properties of (LaXO(3))(2)/(LaAlO(3))(4) (111) with X = 4d and 5d cations. The metastable ferromagnetic phases of LaTcO(3) and LaPtO(3) with preserved P321 symmetry emerge as Chern i...
