IrF4: From Tetrahedral Compass Model to Topological Semimetal
C. Shang, O. Ganter, N. Heinsdorf +1
The intersection of topology, symmetry, and magnetism yields a rich structure of possible phases. In this work, we study theoretically the consequences of magnetism on IrF4, which…
Magnetic anisotropy reversal driven by structural symmetry-breaking in monolayer α-RuCl3
Bowen Yang, Yin Min Goh, Suk Hyun Sung +14
Layered α-RuCl3 is a promising material to potentially realize the long-sought Kitaev quantum spin liquid with fractionalized excitations. While evidence of this exotic state has b…
Combined experimental and theoretical study of hydrostatic (He-gas) pressure effects in -RuCl
B. Wolf, D. A. S. Kaib, A. Razpopov +13
We report a detailed experimental and theoretical study on the effect of hydrostatic pressure on the structural and magnetic aspects of the layered honeycomb antiferromagent -Ru…
Microscopic origin of magnetism in monolayer transition metal dihalides
Kira Riedl, Danila Amoroso, Steffen Backes +7
Motivated by the recent wealth of exotic magnetic phases emerging in two-dimensional frustrated lattices, we investigate the origin of possible magnetism in the monolayer family of…
Magnetic Couplings in Edge-Sharing High-Spin Compounds
Stephen M. Winter
High-spin Co(II) compounds have recently been identified as possible platforms for realising highly anisotropic and bond-dependent couplings featured in quantum-compass model…
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…
