论文摘要
我们在300-860 K的温度范围内使用拉曼光谱法观察了Bifeo $ _3 $中的准弹性光散射（Qels）。Qels具有两个组件：狭窄而宽的成分。宽成分的强度和线宽的温度依赖性在néel点以下和宽QELS之外差异，并且宽QEL可能具有磁性。
We observed quasi-elastic light scattering (QELS) in BiFeO$_3$ 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 Néel point, and the broad QELS may have a magnetic origin.
