TEM and EDS for S3. (a) Cross-sectional TEM and HRTEM images of the specimen S3, show the sequence of layers on the MgO substrate. (b) FFT patterns of the area marked by the squares in (a) containing MgO, Mn\(_{3}\)Ir, CoFe, and Dy. (c) EDS maps of the elements Mg, Ta, Ir, Mn, Dy, Co, and Fe in the layer stack show sharp interfaces along with the HAADF STEM image of the interfaces.
