Abstract

The Ti-O hybridization effect on the ferroelectric phase transition of BaTiO₃ has been studied by resonant-photoemission spectroscopy. The Ti 3d partial-density-of-state in the valence band of the paraelectric phase is larger than that of the ferroelectric phase. This fact indicates that the Ti-O hybridization effect is stronger in the paraelectric phase.
