Abstract

The orbital ordering in LaMnO₃ was investigated using resonance Raman spectroscopy. The spectral ellipsometry was used to determine the corresponding dielectric function. It was observed that the phonon modes with their individual resonance properties yielded a complicated two-phonon spectrum between 1100 cm^-1 and 1300 cm^-1. The results show resonant behavior of the phonon Raman cross section when the laser frequency is close to the orbiton-excitation energy of 2 eV in LaMnO₃.
