In this study, quasi-elastic light scattering (QELS) in BiFeO3 was observed using Raman spectroscopy over a temperature range of 300-860 K. The QELS exhibited two components: narrow and broad ones. The temperature dependence of the intensity and linewidth of the broad component differed below and beyond the Neel point, suggesting a possible magnetic origin of the broad QELS.

The temperature dependence of the intensity and linewidth of the broad component differed below and beyond the Neel point, and the broad QELS may have a magnetic origin.
