GAUSSIAN FLUCTUATIONS OF POLARIZATION IN THE REGION OF PHASE TRANSITIONS IN DMAGAS-DMAALS FERROELECTRICS IN THE FRAMEWORK OF THE FOUR-STATE MODEL
A description of thermodynamics of the DMAGaS-DMAAlS family ferroelectrics improved by taking into account the Gaussian fluctuations of polarization is presented. Fluctuations become important in the vicinity of the second order (or the first order close to the second order) phase transitions which...
