逆自旋霍尔效应已经从30多年前在半导体中预测和发现的一种奇特现象发展成为现代自旋电子学中一种极其重要的效应。它允许自旋电流的检测和转换，沿着探测材料的自旋轨道相互作用。然而，理论和实验结果之间的差异阻碍了自旋电子学这一分支及其应用的发展。在这项研究中，我们分析了在自旋泵实验中高度利用的钇铁石榴石基系统，并证明了在这种系统中逆自旋霍尔效应的正确归一化过程。(C)2015日本应用物理学会
The inverse spin Hall effect has made its way from being a peculiar phenomenon predicted and discovered in semiconductors more than 30 years ago to being an extremely important effect in modern spintronics. It allows for the detection and conversion of spin current, along with the probing of the spin-orbit interaction of materials. However, the discrepancy between theoretical and experimental results has slowed down the progress of this branch of spintronics and its applications. In this study, we analyzed yttrium-iron-garnet-based systems highly exploited in spin pumping experiments and demonstrated the correct normalization procedure for the inverse spin Hall effect in such systems.
