论文摘要
我们在金属铁磁纳米磁体中测量霍尔角的磁场依赖性具有稳定的局部磁矩，在该局部磁力力时，霍尔效应的采用机制分别预测线性以及对外部场的持续依赖性分别来自普通和异常霍尔效应。我们建议，实验观察到的与这种依赖性的偏差是由反旋转霍尔效应（ISHE）引起的，并发展了一种现象学理论，该理论预测了ISHE对外部磁场的贡献的独特非线性依赖性。理论与实验之间的完美一致性支持ISHE在铁磁金属中大厅运输中的重要作用。
We measure magnetic field dependence of the Hall angle in a metallic ferromagnetic nanomagnet with stable local magnetic moments where the adopted mechanisms of Hall effect predict linear plus a constant dependence on the external field originating from the ordinary and anomalous Hall effects, respectively. We suggest that the experimentally observed deviations from this dependence is caused by the inverse spin Hall effect (ISHE) and develop a phenomenological theory, which predicts a unique nonlinear dependence of the ISHE contribution on the external magnetic field. Perfect agreement between theory and experiment supports the considerable role of the ISHE in the Hall transport in ferromagnetic metals.
