Abstract

Pressure dependence of Raman peaks of LaNbO₄ in low frequency region is investigated up to ~44.6 Kbar at room temperature. The lowest frequency mode shows a remarkable increase in frequency and a decrease in peak intensity, in contrast to two other peaks. As a result of the considerable frequency change of the lowest mode, the crossing with a higher frequency mode is observed.
