Abstract
Thermal properties of RS(1-x)-ARS(x) studied by an ac calorimetric tec hnique are reported. In order to obtain better values of the transitio n entropies for the mixed crystals, two problems have remained: evalua tion of absolute value of the specific heat and precise determination of background of the very small anomaly. A method to evaluate the abso lute value using the ac-calorimeter has been developed and determinati on of the background has been improved. Finally refinement of the valu e of the transition entropy are given for these mixed crystals.
