Recent intensive studies on various kagome metallic systems have revealed fascinating electronic phases such as the correlated topological states, charge density wave ordering, and superconductivity. Among them, the Fe–Sn compounds are a well-known system with a complex interplay of topological band structure, electronic correlations, and magnetism. The kagome ferromagnet Fe3Sn has been found to host a topological nodal plane near the Fermi energy and exhibit the large transverse transport responses such as the anomalous Nernst effect (ANE) in bulk samples. In this study, we fabricated the epitaxial thin film of Fe3Sn and investigated the magnetic and transport properties. In the presentation, we will report these results in detail.
