Electronic states and molecular dynamics of single-component molecular conductors [M(tmdt)$_2$] (M=Ni, Pt) studied by $^{13}$C and $^1$H NMR

The molecular conductors [M(tmdt)$_2$] (M=Ni, Pt) consisting of single molecular species are investigated with $^{13}$C NMR and $^1$H NMR. The temperature dependences of $^{13}$C NMR shift and relaxation rate provide microscopic evidences for the metallic nature with appreciable electron correlations. Both compounds exhibit an anomalous...More
