Abstract
We report 13C NMR spectra and spin-lattice relaxation measurements performed on the 13C enriched Ni(dmit)2 molecules in the two-chain organic conductor TTF[Ni(dmit)2]2. The average Knight shift value for all Ni(dmit)2 carbon positions amounts to about 100 p.p.m. between 300 and 100 K and decreases down to about 50 p.p.m. at 10 K. The temperature dependence of the spin-lattice relaxation rate is faster than the linear one. Our data clearly show that the CDW observed previously by structural investigations involves Ni(dmit)2 stacks. However, at variance with other organic conductors, the onset of the CDW state in the present material does not induce any metal-insulator transition. Different possible shapes of Fermi surfaces are discussed.
