Abstract
Ferroelectric perovskites, particularly pure and Fe-doped BaTiO3, show remarkable discontinuities in dielectric and ferroelectric constants at the tetragonal-cubic transition. These discontinuities are discussed quantitatively taking into account the effective electric field acting on the electric dipole moments corresponding to the elementary cells. It is found that the calculated results are in good agreement with the experimental data.
