Field-induced multipolar character in the dipolar ground state of the honeycomb rare-earth chalcohalide NdOF
Tiantian Liu, Yanzhen Cai, Mingtai Xie +6
Field-tunable reconstruction of crystalline electric field (CEF) doublets offers a promising avenue for inducing multipolar character, while its observation in real materials has b…
Origin of anomalous p-type conductivity in monolayer Fe-doped MoS2
Xiangning Quan, Xiaoqiu Yuan, Junwei Zhang +13
Substitutional doping effectively modulates carrier polarity of semiconducting two-dimensional (2D) transition metal dichalcogenides (TMDs) like MoS2. Although Fe doping typically…
Anomalous enhancement of magnetism by nonmagnetic doping in the honeycomb-lattice antiferromagnet ErOCl
Yanzhen Cai, Mingtai Xie, Jing Kang +8
Tuning magnetic anisotropy through chemical doping is a powerful strategy for designing functional materials with enhanced magnetic properties. Here, we report an enhanced Er^3+ ma…
Dominant Kitaev interaction and field-induced quantum phase transitions in triangular-lattice KCeSe2
Mingtai Xie, Zheng Zhang, Weizhen Zhuo +13
Realizing Kitaev interactions on triangular lattices offers a compelling platform for exploring quantum-spin-liquid physics beyond the conventional honeycomb lattice framework. Her…
Gapless spinon excitations emerging from a multipolar transverse field in the triangular-lattice Ising antiferromagnet NaTmSe2
Zheng Zhang, Jinlong Jiao, Weizhen Zhuo +9
The triangular-lattice quantum Ising antiferromagnet is a promising platform for realizing Anderson's quantum spin liquid, though finding suitable materials to realize it remains a…
Crystalline electric field excitations and their nonlinear splitting under magnetic fields in YbOCl
Yanzhen Cai, Wei Ren, Xijing Dai +8
Recently reported van der Waals layered honeycomb rare-earth chalcohalides REChX (RE = rare earth, Ch = chalcogen, and X = halogen) are considered to be promising Kitaev spin liqui…
