概要

• 論文の詳細を見る

• We performed powder neutron diffraction and scattering experiments of the S = I/2 triangular lattice system, BaVS_3, and found magnetic reflections below T_x ≃ 30 K. The propagation vector is determined to be incommensurate (0.226 0.226 O) in the hexagonal index. The ordered moment is roughly, estimated to be 〜 0.5μB/V. Although the elastic magnetic diffractions disappear above T_x, Iow-energy inelastic scattering, which has an Q - ω dispersion similar to that below T_x, was observed between T_x and the metal-insulator transition point T_<MI> ≃- 70 K, indicating the presence of a long-range and dynamic antiferromagnetic correlation, i.e., a spin-liquid-like state, between T_x and T_<MI>
