Superexchange interactions between spin-orbit-coupled 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 and 4 oxides with face-sharing ligand octahedra, BaIr…
Orbital reconstruction in nonpolar tetravalent transition-metal oxide layers
Nikolay A. Bogdanov, Vamshi M. Katukuri, Judit Romhányi +5
A promising route to tailoring the electronic properties of quantum materials and devices rests on the idea of orbital engineering in multilayered oxide heterostructures. Here we s…
Strongly frustrated triangular spin lattice emerging from triplet dimer formation in honeycomb Li2IrO3
Satoshi Nishimoto, Vamshi M. Katukuri, Viktor Yushankhai +5
In quantum magnetism spin dimers are typically associated with spin-singlet states. To date, has not been observed in any 3D or quasi-2D material. With thi…
Mechanism of basal-plane antiferromagnetism in the spin-orbit driven iridate Ba2IrO4
Vamshi M. Katukuri, Viktor Yushankhai, Liudmila Siurakshina +3
By ab initio many-body quantum chemistry calculations, we determine the strength of the symmetric anisotropy in the 5 j 1/2 layered material BaIrO. While the…
Topological states in pyrochlore iridates: long-range anisotropy strongly competing with spin-orbit interaction
Liviu Hozoi, H. Gretarsson, J. P. Clancy +7
In the search for topological phases in correlated electron systems, iridium-based pyrochlores A2Ir2O7 -- materials with 5d transition-metal ions -- provide fertile grounds. Severa…
