Abstract :
In the course of the investigation of the low temperature specific heat of selectively deuterated DCNQI-Cu system with the special interest in the mysterious Metal-Insulator (M-I) transition, we observed an extraordinary excess specific heat around 6K, whose magnitude depends on the distribution of deuteron in (DMe-DCNQI)2Cu. Experimental results predict that the anomalous terms are caused by excess entropies associated with the arrangement of the deuteron in Methyl molecules.
