- Аннотация: Phenomenological models of phase transitions for two interacting order parameters, onecomponentand two-component, are constructed. The construction was carried out based on the numberof control parameters depending on external thermodynamic conditions by methods of the equivariantcatastrophe theory (singularity theory), taking into account the symmetry of the order parameters. Theclassification of phenomenological models according to the number of control parameters is carriedout. Phase diagrams of the models are constructed and the theoretical temperature dependence of theheat capacity is calculated, which shows a satisfactory qualitative correspondence with the experimental dependence in the Rb2KInF6 elpasolite crystal.
