摘　　要：The temperature dependence of the specific heat of the single crystal Pb(In_(0.5)Nb_(0.5))O_(3)-Pb(Mg_(1/3)Nb_(2/3))O_(3)-PbTiO_(3)(PIN-PMN-PT)was obtained at 80–500 K by means of ac-calorimetry,and comparison with the calorimetric data for PMN was made,allowing one to determine absolute values of the specific heat of PIN-PMN-PT.For the high-temperature region(T>200 K),the background heat capacity was calculated,the anomalies of the heat capacity for both compounds were determined,and the hump of the temperature dependence of specific heat PIN-PMN-PT was detected for the first time.
