摘要:
反铁磁材料具有零磁矩或非常小的磁矩,不易受外磁场干扰。相对于铁磁材料,反铁磁材料具有更低的能量损耗和更高的响应频率等优点,因在自旋电子学领域的实际应用方面具有巨大潜力而备受关注。作为一种兼具Kagome晶格及三角反铁磁性的特殊自旋电子学材料,六角Mn3Z(Z=Ga,Ge,Sn)合金展现出巨大的反常霍尔效应、拓扑霍尔效应、自旋霍尔效应以及反常能斯特(Nernst)效应等。这些物理效应涉及到当今凝聚态物理研究中最前沿的问题,对它们的研究不仅可以深化对凝聚态磁性物理的理解,而且也驱动了反铁磁自旋电子学的发展。首先介绍了Mn3Z合金的晶格结构及特殊的磁结构,简要分析了理论计算得到的电子结构对材料输运性能的影响。结合实验报道的Mn3Z的磁性及输运性质等对3种六角结构合金的优异性能及研究进展进行了概述,揭示了磁结构和电子结构对材料输运性质的物理机制,并对Mn3Z系列合金拓扑相关的输运性质进行了展望。
Abstract:
Antiferromagnetic materials exhibit zero or rather low moment, so it would not be affected by external magnetic field. Furthermore, they have advantages of lower power consumption and higher frequency response compared with ferromagnetic materials, which makes them have great potential applications in the field of spintronics. Hexagonal Mn3Z(Z=Ga, Ge, Sn) alloys, with both Kagome lattice and triangular antiferromagnetism, exhibit large anomalous Hall effect, topological Hall effect, spin Hall effect and anomalous Nernst effect. These effects involve the most advanced problems in condensed matter physics. The study of them can not only deepen the understanding of condensed matter magnetic physics, but also drive the development of antiferromagnetic spintronics. In this paper, the research progress in magnetic and transport properties are reviewed. The crystal structure and the special magnetic structure of Mn3Z alloys are introduced. The influence of the electronic structure on the transport properties is briefly analyzed. An overview of the excellent properties of the Mn3Z(Z=Ga, Ge, Sn) alloys and their research progress is given in relation to the experimentally reported magnetic and transport properties. An outlook is given for the topologically relevant transport properties of the Mn3Z alloys.
