We have used molecular beam epitaxy and electronic transport measurements to study the interplay of magnetism and band topology in thin films of the antiferromagnetic kagome metal FeSn. We will present results from a magnetic field and temperature dependent study of the anomalous Hall effect using transverse resistivity measurements. Combining these measurements with magnetic Monte-Carlo simulations and theoretical model calculations, we map out the topological phase diagram of FeSn over a large temperature range.
