Size effect of ferroelectric particles
The surface and size effects of ferroelectric particles have been studied using Landau phenomenological theory, and the Curie temperature, and spontaneous polarization calculated for ferroelectrics with different sizes and second- or first-order phase transition. The size dependence of the extrapola...

| Zusammenfassung: | The surface and size effects of ferroelectric particles have been studied using Landau phenomenological theory, and the Curie temperature, and spontaneous polarization calculated for ferroelectrics with different sizes and second- or first-order phase transition. The size dependence of the extrapolation length of ferroelectric partides is given. The theoretical results agree with the experimental. |
