Abstract

The ¹³C-nuclear magnetic resonance Knight shift at high temperature and 1/(T₁T) at low temperature in A₃C₆₀ compounds was observed. It was shown that the low-T_c materials with small lattice constants showed a decrease in the Fermi level density of states, N(E_F), at low temperatures. The ¹³C-1/(T₁) measurements indicated the appearance of localized spins at low-T. This suggests that an electron-localization start to occur in this system.
