Signatures of a gapless quantum spin liquid in the Kitaev material NaCoZnSbO
Zhongtuo Fu, Ruokai Xu, Yingqi Chen +13
The honeycomb-lattice cobaltate NaCoSbO has recently been proposed to be a proximate Kitaev quantum spin liquid~(QSL) candidate. However, non-Kitaev terms in the Hamilt…
Suppression of the antiferromagnetic order by Zn doping in a possible Kitaev material NaCoTeO
Zhongtuo Fu, Ruokai Xu, Song Bao +13
Very recently, a 3 based honeycomb cobaltate NaCoTeO has garnered tremendous attention due to the proposed proximity to the Kitaev spin-liquid state as its 4/5…
Evidence for strong correlations at finite temperatures in the dimerized magnet NaCuTeO
Yanyan Shangguan, Song Bao, Zhao-Yang Dong +12
Dimerized magnets forming alternating Heisenberg chains exhibit quantum coherence and entanglement and thus can find potential applications in quantum information and computation.…
Disorder-induced broadening of the spin waves in a triangular-lattice quantum-spin-liquid candidate YbZnGaO
Zhen Ma, Zhao-Yang Dong, Jinghui Wang +15
Disorder is important in the study of quantum spin liquids, but its role on the spin dynamics remains elusive. Here, we explore the disorder effect by investigating the magnetic-fi…
Neutron spectroscopy evidence on the dual nature of magnetic excitations in a van der Waals metallic ferromagnet FeGeTe
Song Bao, Wei Wang, Yanyan Shangguan +12
In the local or itinerant extreme, magnetic excitations can be described by the Heisenberg model which treats electron spins as localized moments, or by the itinerant-electron mode…
Topological magnon insulator spin excitations in the two-dimensional ferromagnet CrBr
Zhengwei Cai, Song Bao, Zhao-Long Gu +17
Topological magnons are bosonic analogues of topological fermions in electronic systems. They have been studied extensively by theory but rarely realized by experiment. Here, by pe…
Disorder-induced spin-liquid-like behavior in kagome-lattice compounds
Zhen Ma, Zhao-Yang Dong, Si Wu +14
Quantum spin liquids (QSLs) are an exotic state of matter that is subject to extensive research. However, the relationship between the ubiquitous disorder and the QSL behaviors is…
Evidence of the Berezinskii-Kosterlitz-Thouless Phase in a Frustrated Magnet
Ze Hu, Zhen Ma, Yuan-Da Liao +10
The Berezinskii-Kosterlitz-Thouless (BKT) mechanism, building upon proliferation of topological defects in 2D systems, is the first example of phase transition beyond the Landau-Gi…
Evidence for magnon-phonon coupling in the topological magnet CuTeO
Song Bao, Zhengwei Cai, Wenda Si +11
We perform thermodynamic and inelastic neutron scattering (INS) measurements to study the lattice dynamics (phonons) of a cubic collinear antiferromagnet CuTeO which hosts…
Realization of metallic state in 1T-TaS2 with persisting long-range order of charge density wave
Xin-Yang Zhu, Shi Wang, Zhen-Yu Jia +10
Metallization of 1T-TaS2 is generally initiated at the domain boundary of charge density wave (CDW), at the expense of its long-range order. However, we demonstrate in this study t…
Recent progress on magnetic-field studies on quantum-spin-liquid candidates
Zhen Ma, Kejing Ran, Jinghui Wang +4
Quantum spin liquids (QSLs) represent a novel state of matter in which quantum fluctuations prevent conventional magnetic order from being established, and the spins remain disorde…
Spin-glass ground state in a triangular-lattice compound YbZnGaO
Zhen Ma, Jinghui Wang, Zhao-Yang Dong +19
We report on comprehensive results identifying the ground state of a triangular-lattice structured YbZnGaO to be spin glass, including no long-range magnetic order, prominent b…
Spin-wave excitations evidencing the Kitaev interaction in single crystalline -RuCl
Kejing Ran, Jinghui Wang, Wei Wang +13
Kitaev interactions underlying a quantum spin liquid have been long sought, but experimental data from which their strengths can be determined directly is still lacking. Here, by c…
