Abstract

The organic Mott system of correlated organic superconductors κ-(BEDT-TTF)2X were analyzed using scanning microregion infrared spectroscopy. It was observed that phase separation occurred below critical end temperature 35-40 K of first-order Mott transition. The multiple potential minima of free energy was required in phase separation and the domain grew from nucleation point which should be specific in free energy variation in space. The results show that macroscopic size of domains indicated different class of inhomogeneity from inorganic Mott systems such as high-Tc copper and manganese oxides.
