Abstract
The temperature dependence of the heat capacity of the 0.7PbNi1/3Nb2/3O3-0.3PbTiO3 compound has been studied in the temperature range 120–800 K. The temperature dependence of the heat capacity C p has two diffuse anomalies in the temperature ranges 250–450 K and 450–650 K and a λ anomaly at temperatures T ≈ 225 K. The results are discussed with inclusion of the dielectric and structural data.
