Abstract

We observed ferroelastic domain of LaNbO₄ crystals by micro-Raman spectroscopy utilizing a specific band (107 cm_-1 Ag mode) with the polarization condition. We found the variation of the Raman intensity corresponding to the ferroelastic domain structure, which is caused by the rotation of crystallographic axes in each domain. The results were in accordance with the optical microscope image with a good reproducibility, proving the feasibility of micro-Raman spectroscopy in the study of domain structures.
