a 2θ-ω x-ray scan of the heterostructure of 10 nm Py/30 nm Mn3GaN on LSAT (001) substrate showing single-phase Mn3GaN with thickness oscillations indicating a smooth surface and sharp interface with the substrate. Inset shows reflection high-energy electron diffraction (RHEED) pattern of the specular diffraction spot for the Mn3GaN surface. b Scanning transmission electron microscope image of Py/Mn3GaN heterostructure on (001) LSAT substrate with the top Py/Mn3GaN interface (left), and the bottom Mn3GaN/LSAT interface (right).
