• Topological effects on spin frustration in equilateral triangle $S=3/2$ spin tubes formed in CsCrF4 were studied by magnetic susceptibility, heat capacity [$C(T)$], and electron spin resonance experiments. The experimental data show that there is no magnetic long-range order down to $T=1.3$ K, and that no spin gap due to a chiral spin structure appears. Furthermore, since the $C(T)$ curve has a $T$-linear component, a gapless spin-liquid ground state in one-dimensional antiferromagnets, the so-called Tomonaga–Luttinger liquid, is realized. This is characteristic of equilateral triangle spin tubes with $S$ = half-integer.
