Thermodynamics and dielectric anomalies of DMAAS and DMAGaS crystals in the region of phase transitions (Landau theory approach)
A simple description of thermodynamics of DMAAS and DMAGaS ferroelectric crystals by means of Landau expansion is proposed. Conditions of occurrence of phase transitions are established and their temperatures are obtained. The influence of external hydrostatic pressure on phase transitions is descr...

| description |
A simple description of thermodynamics of DMAAS and DMAGaS ferroelectric crystals by means of Landau expansion is proposed. Conditions
of occurrence of phase transitions are established and their temperatures
are obtained. The influence of external hydrostatic pressure on phase transitions is described. The temperature behaviour of dielectric susceptibility
components and their anomalies in the vicinity of phase transition points
are investigated. The results obtained are compared with the experimental
data. |
