Abstract
It is possible to perform the high frequency measurements of the frequency dependence of heat capacity using so-called 3ω method, in which a thin metal film is used as a heater and a thermometer. The method has been applied to heat capacity spectroscopy with a wide frequency range up to 10kHz. In this paper, the development of the system for simultaneous measurements of the heat capacity spectroscopy and dielectric susceptibility is reported. It is shown that the simultaneous measurements provide the useful information to investigate the correlation between the motions of the dipole moments and the enthalpy relaxation phenomena.
