Abstract:

ill model of the low-temperature orthorombic phase (O') of LaMnO3 was constructed using pair potentials with explicitly allowing for the many-body Jahn-Teller contribution to the crystal energy. The analysis of the structure, elastic constants and phonon frequencies is based on the comparison of the structural phases that obtained with including and ``switching-off{''} Jahn-Teller contribution to the energy and dynamical matrix of the crystal.
