  The topological kagome magnet (TKM) Fe3Sn2 exhibits unusual topological
properties, flat electronic bands, and chiral spin textures, making it an
exquisite materials platform to explore the interplay between topological band
structure, strong electron correlations, and magnetism. Here we report the
first synthesis of high-quality epitaxial (0001) Fe3Sn2 films with large
intrinsic anomalous Hall effect close to that measured in bulk single crystals.
In addition, we measured a large, anisotropic anomalous Nernst coefficient Syx
of 1.26 {\mu}V/K, roughly 2-5x greater than that of common ferromagnets,
suggesting the presence of Berry curvature sources near the Fermi level in this
system. Crucially, the realization of high-quality Fe3Sn2 films opens the door
to explore emergent interfacial physics and create novel spintronic devices
based on TKMs by interfacing Fe3Sn2 with other quantum materials and by
nanostructure patterning.
