Abstract

The high-pressure response of the Sm2.75C60 fulleride is probed by Raman spectroscopy. The Raman spectrum of Sm2.75C60 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.
