Topological magnetic materials display a strong interplay between magnetic and
electronic properties, giving rise to various exotic quantum phenomena such as the
anomalous Hall effect (AHE), the topological Hall effect (THE), and the skyrmion
lattice. On the other hand, the Kagome lattice, in which the atoms are arranged in a
star-like formation, anticipates geometrical frustration leading to noncollinear
antiferromagnetic (AFM) ordering. So far, several Kagome intermetallic systems,
such as Co 3 Sn 2 S 2 , Fe 3 Sn 2 , YMn 6 Sn 6 , Gd 3 Ru 4 Al 12 , etc. have been explored for their
magnetic and topological properties. In this presentation, we discuss the electrical,
magnetic, spectroscopic, and topological properties of Kagome antiferromagnets
