磁性受阻材料因其新颖的自旋相关输运性质而引起人们的极大兴趣。我们报道了三角形巡游铁磁体中的各向异性反常霍尔效应。当电流沿平面流动时，在居里温度以下表现出传统的反常霍尔效应，这可以用Karplus-Luttinger理论来描述。另一方面，拓扑霍尔效应随电流沿轴向出现在下方。霍尔电阻率的提高可以归因于自旋翻转过程中的手征效应。
Magnetic frustrated materials are of great interest for their novel spin-dependent transport properties. We report an anisotropic anomalous Hall effect in the triangular itinerant ferromagnet. When the current flows along theplane,exhibits the conventional anomalous Hall effect below the Curie temperature, which can be depicted by Karplus–Luttinger theory. On the other hand, the topological Hall effect shows up belowwith current along theaxis. The enhancement of Hall resistivity can be attributed to the chiral effect during the spin-flop process.
