Sažetak
We report the first very low temperature (From 93 mK to 7.3 K) specific heat data of a modulated incommensurate dielectric (ClC6H4)(2)SO2. They reveal three different contributions in excess of that of normal acoustic phonons: low frequency excitations predominant below 0.2 K, a phason branch above 0.7 K, and optical phonon and amplitudon branches around 4.5 K. This analysis is done considering neutron scattering results also. [References: 23]
