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.

该项目旨在开发具有磁性元素掺杂剂的高质量稀磁半导体（DMS），用于实际自旋电子学应用。合格的 DMS 的特性包括固有铁磁性、有效的自旋操纵、高自旋极化和长距离自旋输运，这些特性迄今为止尚未得到很好的解决。该项目将使用先进的工具来研究这些问题，包括μ子自旋弛豫和中子反射测量。该项目期望建立评估 DMS 的标准，了解自旋动力学和自旋操纵机制，并实现合格的 DMS。
