K. Kitazume et al., Electronic states, of superconducting fullerides with small lattice constants: a NMR study, SYNTH METAL, 121(1-3), 2001, pp. 1115-1116
We report a systematic NMR study on A(3)C(60) superconducting fullerides, w
here A is alkali metal. It was strongly suggested that the Fermi level dens
ity of states N(E-F) decreases with temperature in materials with low-tempe
rature superconducting transition temperature.
