论文摘要
抗铁磁铁MN $ _3 $$ X $，（$ X $ = Sn，GE，GE）最近发现了惊人的零场大厅和Nernst效应，这使对磁性拓扑状态的研究成为了凝聚态物质研究和技术创新的最前沿。这些效果被认为是居住在费米能源附近的Weyl节点的指纹，促进了Mn $ _3 $$ X $，（$ x $ = Sn，GE），是一个引人入胜的平台，以探索难以捉摸的磁性Weyl费米子。在这篇综述中，我们通过将以前的报告与我们的新型，全面的综合运输测量值结合了MN $ _3 $$ X $，（$ X $ = Sn，GE）的实验和理论研究的见解最新信息。特别是，我们报告了Mn $ _3 $ ge和Mn $ _3 $ SN的MN $ _3 $ GE和Planar Hall效应中特有的磁转运签名，这些签名尚未在早期的研究中找到。此处总结的结果表明，在没有磁化的情况下，磁性韦尔疗法在产生较大的横向反应中的重要作用。
The recent discoveries of strikingly large zero-field Hall and Nernst effects in antiferromagnets Mn$_3$$X$, ($X$ = Sn, Ge) have brought the study of magnetic topological states to the forefront of condensed matter research and technological innovation. These effects are considered fingerprints of Weyl nodes residing near the Fermi energy, promoting Mn$_3$$X$, ($X$ = Sn, Ge) as a fascinating platform to explore the elusive magnetic Weyl fermions. In this review, we provide recent updates on the insights drawn from experimental and theoretical studies of Mn$_3$$X$, ($X$ = Sn, Ge) by combining previous reports with our new, comprehensive set of transport measurements of high-quality Mn$_3$Sn and Mn$_3$Ge single crystals. In particular, we report magnetotransport signatures specific to chiral anomalies in Mn$_3$Ge and planar Hall effect in Mn$_3$Sn, which have not yet been found in earlier studies. The results summarized here indicate the essential role of magnetic Weyl fermions in producing the large transverse responses in the absence of magnetization.
