The samples of silver stearate with the adsorbed organic dye Rhodamine 6G were investigated by means of the dielectric spectroscopy and differential scanning calorimetry (DSC) methods. The signifi cant infl uence of the adsorbed dye on the dielectric properties of silver stearate was detected: the great increase of the dielectric permittivity was observed in the low frequency range. Two endothermic peaks were detected on the
DSC thermogram of the investigated samples.
