It has been found experimentally that the microwave admittance of the tetrathiotetracene iodide [(TTT)2I3] crystal varies with the magnitude of a direct current flowing through the crystal if = 40 GHz, Τ = 300 К). Two processes have been distinguished: a slow process related to the heating of the crystal and a fast process with τ < 10~7 s. The occurrence of this fast process is at odds with the conventional theory for transport processes in organic quasi-one-dimensional metals.
