N2 - The true superconducting phase in rare-earth C60 fullerides Rx C60 (R=Yb and Sm) is not R2.75 C60 previously reported. Moreover, no superconductivity is observed in Sm- C60 fullerides. The phase sequence between Yb- C60 fullerides and Sm- C60 ones as a function of the intercalant concentration of x is shown to be greatly different, although Yb and Sm are the same family of rare-earth elements with the divalent valence state. This can explain the loss of superconductivity in Smx C60 and suggests the true superconducting phase. The whole picture of rare-earth C60 fullerides is described.
