Can the highly symmetric SU(4) spin-orbital model be realized in alpha-ZrCl3?
A. V. Ushakov, I. Solovyev, S. V. Streltsov
We study physical properties of a potential candidate for the physical realization of the SU(4) spin-orbital model - layered alpha-ZrCl3. Both DFT and DFT+U+SOC calculations show t…
Structural transition in AuAgTe4 under pressure
A. V. Ushakov, S. V. Streltsov, D. I. Khomskii
Gold is inert and forms very few compounds. One of the most interesting of those is calaverite AuTe2, which has incommensurate structure and which becomes superconducting when dope…
Old puzzle of incommensurate crystal structure of calaverite AuTe and predicted stability of novel AuTe compound
Sergey V. Streltsov, Valerii V. Roizen, Alexey V. Ushakov +2
It is shown that the long-standing puzzle of incommensurate crystal structure of AuTe can be solved, if this material is considered as a negative charge-transfer system. Using…
Dimerization in honeycomb Na2RuO3 under pressure: a DFT study
D. D. Gazizova, A. V. Ushakov, S. V. Streltsov
The structural properties of Na2RuO3 under pressure are studied using density functional theory within the generalized gradient approximation (GGA). We found that one may expect a…
Unusual magnetism of layered chromium sulfides MCrS2 (M=Li, Na, K, Ag, and Au)
A. V. Ushakov, D. A. Kukusta, A. N. Yaresko +1
MCrS2 compounds (M=Li, Na, K, Cu, Ag, and Au) with triangular Cr layers show large variety of magnetic ground states ranging from 120-degree antiferromagnetic order of Cr spins in…
