反常霍尔效应的适当标度

Proper Scaling of the Anomalous Hall Effect

Yuan Tian, Li Ye, Xiaofeng Jin

摘要:

利用Fe的外延薄膜,我们成功地独立控制了反常霍尔效应中的不同散射过程。这个结果适当地解释了声子的作用,从而清楚地暴露了反常霍尔电阻率与纵向电阻率的标准图的根本缺陷。因此,一个新的标度已经建立,允许明确的识别的内在Berry曲率机制,以及外在的歪斜散射和侧跳机制的异常霍尔效应。

英文摘要:

Working with epitaxial films of Fe, we succeeded in independent control of different scattering processes in the anomalous Hall effect. The result appropriately accounted for the role of phonons, thereby clearly exposing the fundamental flaws of the standard plot of the anomalous Hall resistivity versus longitudinal resistivity. A new scaling has been thus established that allows an unambiguous identification of the intrinsic Berry curvature mechanism as well as the extrinsic skew scattering and side-jump mechanisms of the anomalous Hall effect.
