摘要：

A thermodynamic theory of phase transitions in crystals characterized by the rotational and polarization components has been developed. A list of phase transitions accompanied by the change of the group to a subgroup is compiled for crystals whose thermodynamic potential can be represented by a fourth-order polynomial with respect to the order-parameter components. Spontaneous polarization arising by the mechanism of improper phase transitions provided by the nonlinear relation between the polarization and rotational components is considered.
