  • 六角笼目(Kagome)相拓扑反铁磁材料近年来引起了人们极大的研究兴趣, 这主要是因为它们拥有众多独特的性能, 例如虽然净磁矩跟反铁磁材料一样接近零, 但确有与铁磁性材料强度相当的磁电、磁光和磁热效应, 极具应用价值. 以上的这些特性绝大多数都与其磁结构紧密相关, 然而人们却发现其磁结构对于生长条件和材料成分非常敏感. 因此, 开发一种简单、普适的Kagome相拓扑反铁磁材料磁结构相变测量方法, 对于大多数难以获得高能中子衍射等先进实验手段的实验室来说, 无论是材料的生长优化还是物理现象机理的理解都具有重要的意义. 本文采用脉冲激光沉积方法在($1 \bar{1}02 $)取向的Al2O3单晶衬底上成功外延制备了高质量($ 11\bar{2}0 $)取向的六角Kagome相Mn3Sn薄膜, 并系统地测量了不同温度下该Mn3Sn薄膜的磁性和磁输运特性. 结果发现, 该Mn3Sn薄膜的磁化曲线、霍尔电阻率曲线和磁电阻曲线在其三类磁相变温度中的某些或全部均表现出一定的异常特征. 这些特征可以作为该六角Kagome相Mn3Sn薄膜中磁相变的证据, 甚至用于测量这些磁相变的温度. 本工作有助于进一步推动六角Kagome相拓扑反铁磁材料在自旋电子器件中的应用.
    In recent years, topological antiferromagnetic material with hexagonal Kagome structure has attracted great research interest due to its unique properties. Although its net magnetic moment is close to zero, the topological antiferromagnet exhibits the strong magnetoelectric, the magneto-optical, and the magnetothermal effect, with a strength comparable to that of ferromagnetic material, which makes it highly valuable for various applications. After several years of extensive studies, it has been realized that most of the unique properties of topological antiferromagnet are actually closely related to its magnetic structure. However, it has been found that the magnetic structure of the material is highly sensitive to its chemical composition and growth condition. Therefore, it is crucial to develop a universal and simple method of measuring the magnetic structure and determining the magnetic phase transition of hexagonal Kagome topological antiferromagnetic material, which can severe as a good supplement for the current high-energy neutron diffraction approach that is not accessible for ordinary laboratories. In this study, we have successfully prepared high-quality ($ 11\bar{2}0 $)-oriented hexagonal Kagome antiferromagnetic Mn3Sn thin films on ($1 \bar{1} 02$)-oriented Al2O3 single crystal substrates by using the pulsed laser deposition method. After systematically measuring how the magnetic and transport properties of the Mn3Sn thin film change with temperature, it is found that its magnetization curve, Hall resistivity curve, and magnetoresistance curve exhibit certain anomalous features at some or all of its three magnetic phase transition temperatures. These features can serve as good evidences of magnetic phase transitions in this hexagonal Kagome antiferromagnetic Mn3Sn thin film, or even could be used to measure the temperatures of these magnetic phase transitions. Our work contributes to the further advancement of the application of hexagonal Kagome topological antiferromagnetic materials to spin electronic devices.
