An Origin of ferroelectricity in Perovskite-type oxides is discussed from a viewpoint of relation between lattice dynamics and chemical bonding state, through comprehensive study of a Ca-substitution effect on the ferroelectricity in CdTiO3. The result indicates covalency of constituent elements plays an important role on the ferroelectricity in the perovskite-type oxides.

Ferroelectric material studies, e.g., ferroelectric phase transition of BaTiO3, and CdTiO3, those involving soft-mode phonon, ferroelectric structure and, its materials properties using state-of-the-art first-principles calculations are described.
