研究方向
长期在自旋动力学与自旋电子学领域工作，目前以第一作者或通讯联系作者发表论文28篇，其中包括 Phys. Rev. Lett. 1篇，Phys. Rev. B 4篇，Appl. Phys. Lett. 10篇。近几年来申请人以自旋角动量定向输运与自旋动力学之间的紧密联系为突破口，在自旋整流效应的物理本质与应用开发、针对微纳尺度自旋电子学器件与材料的局域化表征方法、以及自旋霍尔效应的定量表征与微观机理方面取得了多项具有一定原创性及创新性研究成果。在共面波导器件设计与测试方面：我们充分利用共面波导器件的空间电磁场分布特点，系统研究了在不同方向微波磁场的驱动下自旋泵浦效应和逆自旋霍尔效应的全空间角度依赖关系[PRB 94, 134421 (2016)]、非线性自旋动力学效应[APL 108, 192408 (2016)]、有效区分逆自旋霍尔效应与自旋整流效应的实验方法[JAP 117, 17C725 (2015), APL 112, 092406 (2018)]。在铁磁共振的直流电测量方面：基于霍尔效应可实现局域电测量的思路，我们将反常霍尔效应和自旋整流机制相结合[JAP 113, 17C732 (2013)]，开展了磁性微纳结构中自旋动力学研究[APL 102, 202410 (2013), APL 105, 262404 (2015), APL 109, 182406 (2016)]，目前该方法可应用于绝大多数磁性导体。在磁动力学相关物理效应研究方面：我们依据自旋流对自旋动力学的显著影响，开展了PtPd合金中自旋霍尔角、自旋扩散长度、自旋流注入效率与自旋轨道耦合的定量化关系[AEM 2, ** (2016)共同通讯]，Pt/CoNi多层膜中自旋霍尔磁电阻机理[PRB 103, 024415 (2021)]，FeNi/Gd薄膜中温度依赖的阻尼机理[PRB 102, 174439 (2020)]、磁性异质结构中界面DMI机理[APE 12, 103001 (2019)]的研究工作，并可以在外加偏压的情况下借助铁磁共振研究磁电耦合机制[APL 105, 262404 (2014)]与Mn2Au薄膜的反铁磁自旋霍尔效应[Nat. Mater. (2021) https://doi.org/10.1038/s41563-021-00946-z合作]。在谐振腔磁动力学研究方面：我们与加拿大曼尼托巴大学胡灿明教授合作，基于圆柱形[NJP 21, 065001 (2019)合作]和十字型[PRB 101, 064404 (2020)合作]谐振腔系统研究了光子与磁子之间的相互作用，并发现了它们耦合形成的极化子表现出类似于霍尔效应的横向反射现象[ Nat. Commun. 10:2934(2019)合作]。
