Second-Order Raman Scattering in Ferroelectric Ceramic Solid Solutions LiNb<sub>x</sub>Ta<sub>1−x</sub>O<sub>3</sub>
In the second-order Raman spectra of ceramic solid solutions, LiNb<sub>x</sub>Ta<sub>1−x</sub>O<sub>3</sub> weak overtone bands of fully symmetric fundamental polar excitations were observed for the first time. The frequencies of the two bands exceeded the value o...
