Disorder-induced excitation continuum in a spin-1/2 cobaltate on a triangular lattice
Bin Gao, Tong Chen, Chien-Lung Huang +12
A spin-1/2 triangular-lattice antiferromagnet is a prototypical frustrated quantum magnet, which exhibits remarkable quantum many-body effects that arise from the synergy between g…
Disorder-enriched magnetic excitations in the Kitaev quantum spin liquid candidate NaCoTeO
Li Xiang, Ramesh Dhakal, Mykhaylo Ozerov +9
Using optical magneto-spectroscopy, we investigate the magnetic excitations of NaCoTeO in a broad magnetic field range () at low tempe…
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…
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…
