Anomalous Hall Effect in Kagome Ferrimagnet GdMn6Sn6
Abstract
We present magnetotransport data on the ferrimagnet GdMn6Sn6. From the temperature-dependent data we are able to extract a large intrinsic contribution to the anomalous Hall effect σintxz ~ 32 Ω–1 cm–1 and σintxz ~ 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. Furthermore 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 MgFe6Ge6 structure type a promising system to tune the electronic and magnetic properties in future studies.
