Transition-metal kagome magnets provide a rich platform for investigating the interplay between layer stacking, magnetic order, and band topology. Here, we report the molecular beam epitaxy and experimental investigation of high-quality thin films of the kagome metal Co₃Sn, which has not been synthesized in bulk form yet. Structural and chemical analyses confirm a hexagonal lattice structure (P6₃/mmc) composed of direct A-B stacked Co₃Sn kagome bilayers. Magnetometry reveals robust easy-plane ferromagnetism with a Curie temperature exceeding 300 K. Magneto-transport measurements demonstrate metallic behavior (carrier density n≈5.01×10²² cm⁻³) alongside a temperature-independent anomalous Hall conductivity of σ_(rm AHE)≈90 Ω⁻¹·rm cm⁻¹, extending from 2 K up to room temperature. Results from first-principles density functional theory calculations attribute this anomalous Hall response to intrinsic Berry curvature hotspots near the Fermi level in the spin-split band structure. Our results establish Co₃Sn as a room-temperature kagome ferromagnet and highlight the impact of the layer stacking sequence on the material properties of kagome metals from the CoSn family.
