抄録

The high-pressure response of the Sm2.75C60 fulleride is probed by Raman spectroscopy. The Raman spectrum of Sm2.75C 60 and its pressure evolution differ significantly from those of pristine C60. The initial well-resolved Raman spectrum of the fulleride disappears above 4GPa. This change is reversible; however, the original low-pressure Raman profiles are recovered only below 2GPa. These observations are in line with the pressure-induced hysteretic phase transition of the compound observed earlier by X-ray diffraction and the proposed insulator to metal transition.
