论文摘要
我们在Ferrimagnet GDMN $ _6 $ sn $ _6 $上介绍MagnetTransport数据。从与温度相关的数据中，我们能够提取对异常霍尔效应$σ_{xz}^{int}^{int} \ sim $ 32 $ 32 $ω^{ - 1} cm^{ - 1} $和$σ_{xy} {xy}^$ 223 $ 223 $ 2} cm^compotect在其他系统中还包含过渡金属的库姆网。从我们的运输各向异性以及我们的密度功能理论计算中，我们认为该系统在电子上最好地描述为三维系统。因此，我们表明降低性并不是获得对运输特性的大型浆果阶段贡献的强大要求。此外，稀土和过渡金属磁性的共存使六角形MGFE $ _6 $ ge $ _6 $结构类型A类型A在未来研究中调整电子和磁性的有希望的系统。
We present magnetotransport data on the ferrimagnet GdMn$_6$Sn$_6$. From the temperature dependent data we are able to extract a large instrinsic contribution to the anomalous Hall effect $σ_{xz}^{int} \sim$ 32 $Ω^{-1}cm^{-1}$ and $σ_{xy}^{int} \sim$ 223 $Ω^{-1}cm^{-1}$, which is comparable to values found in other systems also containing kagome nets of transition metals. From our transport anisotropy, as well as our density functional theory calculations, we argue that the system is electronically best described as a three dimensional system. Thus, we show that reduced dimensionality is not a strong requirement for obtaining large Berry phase contributions to transport properties. In addition, the coexistence of rare-earth and transition metal magnetism makes the hexagonal MgFe$_6$Ge$_6$ structure type a promising system to tune the electronic and magnetic properties in future studies.
