Non-collinear antiferromagnet D019-Mn3Sn has attracted much attention owing to its unique physical properties and functionalities. For further exploration, comprehensive characterization of crystalline structure and magnetic/magnetotransport properties is of great importance. Here, we systematically investigate these fundamental properties of Mn3Sn thin film as a function of thickness and discuss the correlation between each parameter. From the obtained results, we infer that 2-fold magnetic anisotropy is correlated with lattice parameter through the strain as pointed out in a previous report and saturated Hall conductivity is affected by a formation of D019 structure. This work is an important step towards developing functional devices based on non-collinear antiferromagnetic thin film.
