To Thermodynamics and Kinetics of Second Order Phase Transitions.
Yu.L. Klimontovich

Thermodynamic and fluctuational characteristics for all values of temperature have been calculated for the simplest model of ferro-electrics in the critical region of the second order phase transition. The kinetic equation for the local density function for the vector of electric polarization has been used as a basis for the calculations. The self-consistent equations for the first and second moments have been used for the description of mono- and poly-domain states appropriately . The obtained theoretical results have been compared with experimental data.
Key words: kinetics, phase transition, critical point, ferroelectrics
