Correlation Induced Magnetic Topological Phases in Mixed-Valence Compound SmB6
Huimei Liu, Moritz M. Hirschmann, George A. Sawatzky +2
SmB6 is a mixed-valence compound with flat f-electron bands that have a propensity to magnetism. Here, using a realistic Gamma8 quartet model, we investigate the dynamical spin sus…
Exchange interactions in Kitaev materials: From NaIrO to -RuCl
Huimei Liu, Jiri Chaloupka, Giniyat Khaliullin
We present an analytical study of the exchange interactions between pseudospin one-half ions in honeycomb lattices with edge-shared octahedra. Various exchange channels inv…
Towards Kitaev Spin Liquid in 3d Transition Metal Compounds
Huimei Liu
This paper reviews the current progress on searching the Kitaev spin liquid state in 3d electron systems. Honeycomb cobaltates were recently proposed as promising candidates to rea…
Kitaev Spin Liquid in 3d Transition Metal Compounds
Huimei Liu, Jiri Chaloupka, Giniyat Khaliullin
We study the exchange interactions and resulting magnetic phases in the honeycomb cobaltates. For a broad range of trigonal crystal fields acting on Co2+ ions, the low-energy pseud…
Spin waves and spin-state transitions in a ruthenate high-temperature antiferromagnet
H. Suzuki, H. Gretarsson, H. Ishikawa +16
Ruthenium compounds play prominent roles in materials research ranging from oxide electronics to catalysis, and serve as a platform for fundamental concepts such as spin-triplet su…
Pseudo Jahn-Teller Effect and Magnetoelastic Coupling in Spin-Orbit Mott Insulators
Huimei Liu, Giniyat Khaliullin
The consequences of the Jahn-Teller (JT) orbital-lattice coupling for magnetism of pseudospin J_{eff}=1/2 and J_{eff}=0 compounds are addressed. In the former case, represented by…
