Silvanite AuAgTe: a rare case of gold superconducting material
Yehezkel Amiel, Gyanu P. Kafle, Evgenia V. Komleva +13
Gold is one of the most inert metals, forming very few compounds, some with rather interesting properties, and only two of them currently known to be superconducting under certain…
Orbital-slective behaviour in cubanite CuFe2S3
E. A. Pankrushina, A. V. Ushakov, M. M. Abd-Elmeguid +1
Using {\it ab initio} band structure calculations we show that mineral cubanite, CuFeS, demonstrates an orbital-selective behavior with some of the electrons occupying mole…
The origin of ferromagnetic interactions in NaMnCl: how the response theory reconciles with Goodenough-Kanamori-Anderson rules
I. V. Solovyev, A. V. Ushakov, S. V. Streltsov
The on-site Coulomb repulsion is the key ingredient for describing the magnetic properties of Mott insulators, leading to a popular believe that many limitations of the density…
Ab initio guided minimal model for the "Kitaev" material BaCo(AsO): Importance of direct hopping, third-neighbor exchange and quantum fluctuations
Pavel A. Maksimov, Alexey V. Ushakov, Zlata V. Pchelkina +3
By considering two {\it ab initio}-based complementary approaches, we analyze the electronic structure and extract effective spin models of BaCo(AsO), a honeycomb mater…
Microscopic origins and stability of the ferromagnetism in CoSnS
I. V. Solovyev, S. A. Nikolaev, A. V. Ushakov +3
Based on the density functional theory, we examine the origin of ferromagnetism in the Weyl semimetal CoSnS using different types of response theories. We argue that th…
Multiple field-induced phases in the frustrated triangular magnet CsFeBr
D. Brüning, T. Fröhlich, D. Gorkov +13
The recently discovered material CsFeBr contains FeBr bi-octahedra forming triangular layers with hexagonal stacking along the axis. In contrast to isostruc…
