Abstract
We present the specific heat measurements performed on (N(CH3)4)2FeCl4 from 60K to 350K by Adiabatic Calorimetry. Phase transition temperatures as well as the corresponding values of the thermodynamic functions have also been determined. In addition, experimental results on the relaxation times as a function of temperature reveal a new and simple technique to study the evolution of the sample thermal conductivity around solid-solid phase transitions.
