Abstract

A fulleride Sm₆C₆₀ has been synthesized using the high-temperature solid-state reaction. The Rietveld refinement on high-resolution synchrotron x-ray powder-diffraction data shows that Sm₆C₆₀ is isostructural with body-centered-cubic A₆C₆₀(A=K, Ba). The Raman spectrum of Sm₆C₆₀ is similar to that of Ba₆C₆₀, and the frequencies of two Ag modes in Sm₆C₆₀ are nearly the same as that of Ba₆C₆₀, suggesting that Sm is divalent and hybridization between C₆₀ molecules and the Sm atom could exist in Sm₆C₆₀. Resistivity measurement shows a weak T-linear behavior above 180 K; the transport at low temperature is mainly dominated by granular-metal theory.
