Excitation and control of magnetization dynamics by nonlocal spin injection

本项目的主要目标是深入理解纯自旋电流与高频磁化动力学之间的相互作用。这将通过探索一种新的极其灵活的动力学系统来实现，在该系统中，通过使用非局域自旋注入机制来产生自旋流。与以前研究的使用自旋极化电流或由自旋霍尔效应产生的纯自旋电流的系统相比，该系统具有许多优点。还将探讨非局域自旋注入装置在自旋电子学和磁微子学中的技术应用的可能性。

The main goal of this project is to achieve the deep understanding of the interaction between pure spin currents and the high-frequency magnetization dynamics. This will be done by exploring a new extremely flexible dynamical system, where spin currents are produced by using the nonlocal spin injection mechanism. This system provides numerous advantages in comparison with previously studied systems operating with spin-polarized electric current or pure spin current created by the spin-Hall effect. The possibilities of technical applications of nonlocal spin-injection devices in spintronics and magnonics will be investigated, as well.
