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…
Pseudospin exchange interactions in d^7 cobalt compounds: Possible realization of the Kitaev model
Huimei Liu, Giniyat Khaliullin
The current efforts to find the materials hosting Kitaev model physics have been focused on Mott insulators of d^5 pseudospin-1/2 ions Ir^{4+} and Ru^{3+} with t_{2g}^5(S=1/2, L=1)…
La1-xBi1+xS3 (x~0.08): An n-Type Semiconductor
Fei Han, Huimei Liu, Christos D. Malliakas +4
The new bismuth chalcogenide La0.92Bi1.08S3 crystallizes in the monoclinic space group C2/m with a = 28.0447(19) Å, b = 4.0722(2) Å, c = 14.7350(9) Å, and = 118.493(5)°. The st…
