Temperature-driven sodium-ion dynamical-to-static crossover in the zig-zag ordered phase of NaCoO
Shangfei Wu, Hengxin Tan, Dong Wu +7
The study combines polarization‑resolved Raman spectroscopy and first‑principles calculations to reveal a temperature‑driven dynamical‑to‑static crossover of sodium ions in Na0.5Co…
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…
Emergent Dispersive Multipolar Excitations in NaErSe
Zheng Zhang, Mingfang Shu, Mingtai Xie +6
In most condensed-matter systems, local and collective excitations remain decoupled due to their distinct energy scales. Here, we identify coupled local-collective excitations in t…
Spectrum and low-temperature bulk properties of triangular quantum spin liquid candidate NaYbSe
A. O. Scheie, Minseong Lee, Kevin Wang +18
We report neutron scattering, pressure-dependent AC calorimetry, and AC magnetic susceptibility measurements of triangular lattice NaYbSe. We observe a continuum of scattering,…
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…
