摘要：

The temperature dependences of the permittivity and specific heat of a mixed (1 − x)PbNi1/3Nb2/3O3-xPbTiO3 system (where x = 0.3, 0.4, 0.5) have been studied over a wide temperature range 290–700 K. It has been shown that the composition with x = 0.3 undergoes a diffuse phase transition at Tm ≈ 315 K. A specific heat anomaly that is characteristic of the phase transition has been revealed at T ≈ 315 K in all the compositions under study.
