研究兴趣:

1.自旋电子学:从降低磁阻尼和提高界面电流-自旋流转换效率两个方面,探究实现具有低临界翻转电流的自旋轨道力矩-磁随机存储器(SOT-MRAM)原型器件。

2.界面自旋轨道耦合理论:SOT-MRAM商业化实现的核心之一是高效的自旋轨道力矩。界面自旋轨道耦合效应诱导的电流-自旋流转换效率远大于块体内的转换效率。利用其增强电流-自旋流转换效率,是实现高效自旋轨道力矩的一个有效途径。

3. 界面磁电耦合理论:高电流带来的高焦耳热损耗是自旋轨道力矩器件商业化面临的一个关键问题。磁性的电场调控具有无(极小)热损耗的特点,使其在低功耗、高效率的自旋电子学器件领域有着广泛的应用前景。但是,如何实现大的磁电耦合系数,一直是电控磁的关键核心。考虑到在纳米薄膜体系下,界面占据的作用越来越重要,基于界面效应的磁电耦合是获得大磁电耦合系数的关键。

4.柔性磁动力学理论:柔性材料不仅在无线传输、可穿戴器件、电子皮肤、三维打印、医疗器械等方面有着广阔的应用前景;而且可以打破硬基地对于材料的限制,实现远大于传统手段的调控能力。但是,一方面,用于描述均匀、平直材料的磁动力学理论,LLG方程,在弯曲条件下面临失效的困境;另一方面,柔性铁磁材料中磁矩分布随材料弯曲变化规律的理论研究还比较匮乏。针对上述问题,建立了柔性磁动力学理论是相当急迫和重要的。

5.微磁学模拟以及第一性原理计算:用于模拟低临界翻转电流的自旋力矩器件、电控磁相关器件以及相关界面效应的微观起源。
