In this paper we report the measurements of the thermally induced depolarization currents in a metallorganic liquid crystal. The depolarization current dependence on temperature has been interpreted in term of an internal electric field set up during the cooling down of the sample under a d.c. external applied voltage. The transition temperature shift verifies a Clausius-Clapeyron type equation also giving evidence of the saturation of the polarization. By analyzing the experimental data, we can hypothesize that there is a double order in the system: the nematic order, concerning the director n which behaves quite normally, and an electric order, concerning the electric dipoles. Whereas the first type of order induces a phase in the system (the nematic phase) it is doubtful that the second ones induces a real phase in the system.
