Abstract
Ferroelectric microregion (FMR) in SrTiO3 has been studied by means of Raman scattering. With lowered temperature, FMR, shape of which is ellipsoidal, increases the size concurrently with the correlation length. The ferroelectric transition of solid solution system such as Sr1−x Ca x TiO3 sets in when the FMR occupy the whole crystal volume. These characteristics are common to FMR in KTa1−x Nb x O3.Keywords
