Abstract

Static and dynamical properties of Cu²⁺ (3d⁹; S = 1/2) spins in a twisted Heisenberg triangular spin tube, [(CuCl ₂tachH)₃Cl]Cl₂, have been investigated by nuclear magnetic resonance (NMR) and magnetization measurements in the temperature range T 0.05-300 K. Magnetization curves below 0.5 K show a clear change in slope around 5 T, attributed to a signature of 1/3 plateau in magnetization. From a systematic measurement of nuclear spin-lattice relaxation rates as a function of temperature and external field, the fluctuation frequency of Cu²⁺ spins is found to decrease with decreasing temperature, revealing an unusual slow spin dynamics at low temperatures.
