Transition metal - tin alloys have been paid attention as materials for spintronics devices in recent years. For example, D0₁₉ Mn₃Sn which is frustrated antiferromagnetic material was reported to exhibit large anomalous Hall effect because of its Berry curvature of Weyl points. On the other hand, Fe₃Sn₂ and Fe₃Sn were expected to show intrinsic anomalous Hall effect which is useful for Hall sensor. For the applications, high-quality epitaxial growth of these materials is indispensable, however it has not been achieved yet. In this work, we fabricated D0₁₉ type Fe₃Sn and Mn₃Sn epitaxial films and measured their physical properties. In addition, we compared magneto-transport properties of D0₁₉ and B2 Fe₃Sn which we developed recently.
