Abstract

The electronic states of the non-superconducting Li₂CsC₆₀ and the superconducting Li₂CsC₆₀ were studied by ¹³³Cs-, ⁷Li- and ¹³C-NMR. The results were compared with those of other alkali(A)-doped C60 compounds, A₃C₆₀. We could not find any reason for the suppression of superconductivity in Li₂CsC₆₀ in the NMR data taken at room temperature. Alternatively, the sp³-like carbons were suggested to exist in Li₂CsC₆₀ below ∼160 K.
