The giant anomalous Hall effect in the ferromagnet Fe<sub>3</sub>Sn<sub>2</sub>—a frustrated kagome metal
We have investigated magnetic and transport properties of the {\it kagom\'{e}-bilayer} ferromagnet Fe$_{3}$Sn$_{2}$. A soft ferromagnetism and a large anomalous Hall effect are observed. The saturated Hall resistivity of Fe$_{3}$Sn$_{2}$ is 3.2 $\mu\Omega$cm at 300 K, which is almost 20 times higher than that of typical itinerant-ferromagnets such as Fe …
