Here we present the ultrasonic study of elastic properties of the molecular fullerite C60 in the temperature range 80-300 K at pressures up to 1.4 GPa. We have determined for the first time the pressure dependencies of shear modulus and Poisson's ratio. Particularly, the Poisson's ratio was found to increase from ≈0.3 at ambient pressures to ≈0.38 at p = 1 GPa. The observed high values of the Poisson's ratio, as well as high values of the pressure derivatives of bulk modulus ≈23-25, are discussed in terms of the central m-n power potential and contribution of the noncentral intermolecular forces. |
