Abstract

7Li- and 51V-NMR have been measured to make clear the electronic state in a two-dimensional triangular lattice LiVS2. Knight shift of both 7Li- and 51V-NMR is almost independent of temperature below the phase transition temperature Tc of about 310 K from the paramagnetic state to non-magnetic state. The 51V- spin-lattice relaxation rate 1 / T1 reveals an exponential temperature dependence below Tc, indicating a gap structure of electronic state. These results are consistent with a non-magnetic state with a trimer singlet of V3 + spins below Tc.
