Antiferromagnetic materials could represent the next step in spintronic applications, since antiferromagnets do not produce stray fields, are robust to external perturbations from magnetic fields, and show ultra-fast spin dynamics and current-induced phenomena. The non-collinear chiral antiferromagnets have attracted much interest, due to their remarkable structural, magnetic and electro-transport properties [1]. Here, we present the structural and magnetic properties of antiferromagnetic Mn₃Sn films with hexagonal D0₁₉ structure. For this purpose, we performed systematic X-ray diffraction (XRD), transmission electron microscopy (TEM), and magnetic characterization of films heteroepitaxially grown on appropriate substrates.
