XRD for S1, S2, and S3. X-ray diffraction patterns of the epitaxial Mn\(_{3}\)Ir (S1, S2 and S3) and CoFe (S1, S3) indicating the main structural peaks from the layers. The Dy peaks (S2 and S3) correspond to the various polycrystalline phases. Additionally, various peaks are seen from the capping layer (TaN) and substrate (MgO).
