Abstract

Polarized Raman scattering and infrared absorption measurements were carried out in FePS3 and FePSe3 as a function of temperature. Features at 700-2000 cm−1 are shown to be essentially due to transitions among the trigonal-field-split 5T2g multiplet of the Fe2+ iron and their phonon sidebands. Though the unpolarized Raman spectra are similar in both compounds, polarized spectra are markedly different. We propose a tentative model to account for this.
