本文研究了Ni81Fe19/Pt薄膜自旋泵浦引起的电动势磁化强度的极角依赖性，以检验逆自旋霍尔效应（ISHE）的模型。在实验中，通过同时测量铁磁共振场和电动势信号，直接估计了电动势的磁化方向依赖性。利用Landau-Lifshitz-Gilbert方程结合ISHE模型进行计算，得到了较好的实验结果。
The polar-angular dependence of the magnetization in electromotive force induced by the spin pumping has been investigated for a Ni81Fe19/Pt film to examine the model of the inverse spin-Hall effect (ISHE). In the experiment, the magnetization-direction dependence of the electromotive force is estimated directly by the simultaneous measurement of the ferromagnetic resonance field and the electromotive force signal. The experimental results are well reproduced by a calculation based on the Landau-Lifshitz-Gilbert equation combined with the ISHE model.
