Abstract:
The lattice dynamics of regular LaMnO3 is calculated within a shell model with pairwise interionic interaction potentials and with a Jahn-Teller (JT) contribution included into the energy and dynamic matrix of the crystal. A correlation is made between Raman spectral lines and lattice vibrations. The positions of some lines in the Raman spectrum are found to depend heavily on the linear JT coupling constant V-e. The effect of the JT coupling on the phonon density of states of LaMnO3 is investigated. (C) 2001 MAIK ``Nauka/Interperiodica{''}.
