摘要：

The anomalous (nonclassical) behavior of the heat capacity in the region of the second-order phase transition “initial phase–incommensurate phase” was experimentally observed in the SC(NH2)2 ferroelectric. Such a critical behavior of heat capacity above and below the temperature of incommensurate phase transition is shown to be qualitatively consistent with the fluctuation theory of XY-type systems.
