Abstract
Triangle spin tube viewed from tube direction is topologically equivalent to kagomé lattice. The rung (J1) and inter-tube (J2) interactions on triangle spin tube correspond respectively to the next nearest neighbor and the nearest neighbor interactions on kagomé lattice. In the case of J1>0 (Antiferromagnetic) and J1>>|J2|, the ground state is q=0,120∘ structure with J2>0 or Cuboc state that represented multi-q (q=2π(1/2 0) and two symmetric-equivalent vectors) with J2<0 [1]. CsCrF4 is a perfect triangle spin tube material with antiferromagnetic intra-tube and rung interactions [2]. Neutron diffraction measurement revealed magnetic long-range order at T=1.5 K. Contrary to the expectation, the magnetic structure was determined q=2π(1/2 0 1/2), 120∘ structure by Rietveld refinement. We also confirmed that this structure was stabilized by Dzyaloshinskii -Moriya interaction and small anisotropy that obeyed the three-fold symmetry at Cr sites by calculation. © 2021 American Physical Society
