A possible demonstration of cooperative dynamical Jahn-Teller effect in Raman scattering spectrum of rhombohedral $LaMn{O}_3$

S. E. Popov, A. E. Nikiforov

The Raman scattering (RS) spectra of rhombohedral $LaMn{O}_3$ is considered. It is shown that broad high intensity RS line at 640 $c{m}^{-1}$ could be explained in the framework of coo…
