Observation of quasi-elastic light scattering in BiFeO3
Abstract
We observed quasi-elastic light scattering (QELS) in BiFeO3 using Raman spectroscopy over a temperature range of 300-860 K. The QELS has two components: a narrow and broad component. The temperature dependence of the intensity and linewidth of the broad component differed below and beyond the N\'eel point, and the broad QELS may have a magnetic origin.
