We report on an accurate low-temperature specific heat $(C_{\rm p})$ study of several icosahedral AlCuFe samples of high structural quality in a broad $(0.1\lesssim T\lesssim 10$ K) temperature interval. The analysis shows deviations of $C_{\rm p}$ from the standard $\gamma T$ and $(\beta T^3 + \delta T^5)$ variations, generally well obeyed in crystalline (semi-)metallic alloys in this $T$-range for the electronic and phonon contributions respectively. We relate the unusual vibrational heat capacity to the very peculiar behaviour of vibrational states in quasicrystals, characterized by numerous dispersionless modes, broadened in energy, and extending down to low frequency. On the other hand, sub-linear variations of $C_{\rm p}$ at very low ...
