Spin manipulation in oxide magnetic semiconductors towards spintronics applications

该项目旨在开发具有磁性元素掺杂的高质量稀释磁性半导体（DMS），用于自旋电子学的实际应用。合格DMS的性质包括本征铁磁性、有效的自旋操纵、高自旋极化和长距离自旋输运，这些迄今尚未得到很好的解决。这个项目将使用先进的工具来研究这些问题，包括介子自旋弛豫和中子反射计。本项目旨在建立评价DMS的标准，了解自旋动力学和自旋操纵机制，并获得合格的DMS。

The project is to develop high quality diluted magnetic semiconductors (DMS) with magnetic element dopant for practical spintronics applications. The properties for the qualified DMS include intrinsic ferromagnetism, effective spin manipulation, high spin polarisation and long distance of spin transport, which have not been well addressed so far. This project will investigate these issues using advance tools, including muon spin relaxation and neutron reflectometry. This project expects to establish criteria for evaluating DMS, understanding spin dynamics and mechanisms of spin manipulation and achieve qualified DMSs.
