Abstract

Polarized Raman scattering spectra of LiGa5O8 are observed at room temperature. Two adjacent peaks are newly found in a low frequency region (128 and 135 cm−1). By the site symmetry consideration, we concluded that these peaks correspond to the doubly degenerate and the non-degenerate modes of the translational motion of GaO4 at the tetrahedral site. These two modes are the ones derived by splitting of the triply degenerate translational mode in the disordered state when the order-disorder transition occurs at 1140°C.
