Effect of the change of electrostatic constraints on the phase transitions of some phenomenological models of ferroelectrics
Keyword(s):
The effects of changes of electrostatic constraints on the ferroelectric phase transition are described. The discussion is based on a system consisting of a parallel-plate condenser with a dielectric slab insert. The material of the slab is assumed to be a ferroelectric with an equation of state, in the direction normal to the plates, of the form E = A(θ − θ0)D + ξD3 + ζD5. As the plate separation of the condenser is changed, the nature of the phase transition may change. The results are presented in the form of phase diagrams.
