Superexchange interactions between spin-orbit-coupled $j\approx 1/2$ ions in oxides with face-sharing ligand octahedra

Lei Xu, Ravi Yadav, Viktor Yushankhai +3

Using ab initio wave-function-based calculations, we provide valuable insights with regard to the magnetic exchange in 5$d$ and 4$d$ oxides with face-sharing ligand octahedra, BaIr…
