- Abstract
- The specific heat of fullerenes extract (C60/C70) has been measured in the temperature range 4 < T < 560 K. The temperature variation of the specific heat exhibits an anomalous behaviour. Below 80 K, it presents a classical temperature variation with a dependence close to a T3 below 10 K. The measurements bring two transitions to the fore : one around 250 K corresponding to the well known orientational phase transition, and the other around 90 K which is attributed to the freezing of the rotational motion of the molecules.
