Abstract :
Systematic 13C-NMR studies have been performed for t1g-derived fullerene compounds, A3Ba3C60 (A=K, Rb and Cs) and AExC60 (AE=Sr,Ba, x=3,4,6) in the temperature range of 4.2-300 K. In the t1g-superconducting compounds, the density of states at Fermi level N(EF) at carbon site are found to be considerably small in comparison with t1u-derived superconducting A3C60. The static and dynamic properties will be discussed.
