摘要

利用x射线吸收光谱（XAS）、磁圆二色性（XMCD）和磁康普顿谱分析研究了Li共掺杂对过渡金属掺杂ZnO的电子和磁性能的影响。研究结果表明，在较宽的温度范围内，8% Li浓度的Co掺杂增强了ZnO:Co的电子结构，同时稳定了磁相互作用，磁矩约为3.00 μB。XAS结果强调了Li通过改变自旋和轨道贡献来调节磁相互作用的重要性，这对于实现高性能的磁性器件是必不可少的。这些发现为未来的实验和理论研究提供了一个强大的框架，旨在为未来的技术应用定制铁磁半导体的特性。

Influence of Li codoping on the stability of ferromagnetism in Co-doped ZnO

We investigate the effects of Li codoping on the electronic and magnetic properties of transition metal-doped ZnO using X-ray absorption spectroscopy (XAS), magnetic circular dichroism (XMCD), and magnetic Compton profile analyses. Our findings reveal that Co doping with an 8% concentration of Li enhances the electronic structure of ZnO:Co over a wide temperature range while stabilizing the magnetic interactions with magnetic moments

. XAS results highlight the importance of Li in tuning the magnetic interaction through modifications of the spin and orbital contributions, which are essential for achieving high-performance magnetic devices. These findings provide a robust framework for future experimental and theoretical studies aimed at tailoring the properties of ferromagnetic semiconductors for future technological applications.
