By employing molecular dynamics simulations, we study thermal relaxation in two types of nanoclusters, a cubelike stack of identical carbon nanotubes and a nanocube of fullerene C(60) molecules. We calculate relaxation time and coefficient of thermal conductivity and reveal that the C(60) nanocluster demonstrates anomalously slow thermal relaxation due to the excitation of long-lived internal localized oscillatory modes. This suggests that such nanoclusters would be the most efficient for photophoretic manipulation of fullerenes.
