Abstract

¹H-NMR measurements of [Ph(NH)₃](18-crown-6)[Ni(dmit)₂] having two-leg spin ladder structure were performed. The nuclear spin-lattice relaxation rate (T₁^-1) showed a sharp drop at 50 K. The temperature dependence was fitted by activation-type formula, whose gap was in good arrangement with the spin gap estimated by magnetic susceptibility measurements.
