Abstract

Raman spectroscopy has been used to investigate the domain structures in bismuth-layered-structured ferroelectrics (BLSFs). In Bi₄Ti ₃O₁₂ single crystal, the lowest frequency mode (soft mode) at ∼30 cm^-1 appears exclusively for the xx polarization configuration (x||polar axis). We found that the polarization dependence of the Raman signal exhibits spatial symmetries that reflect the presence of different domain variants present in Bi₄Ti₃O₁₂. This highly anisotropic character of the soft mode shares with other BLSFs such as Bi_3.25La_0.75Ti₃O₁₂ and SrBi ₂Ta₂O₉, which demonstrate the usefulness of the soft-mode spectroscopy for the study of ferroelectric domain structures in BLSFs. We also applied Raman spectroscopy to in situ observation of domain structures in Bi₄Ti₃O₁₂ under applied electric field.
