Z-Contrast STEM Imaging of Long-Range Ordered Structures in Epitaxially Grown CoPt Nanoparticles

Figure 3

HAADF-STEM images and corresponding FFT patterns of L1₀-CoPt nanoparticles: (a) single-crystal nanoparticle formed after annealing at 973 K for 100 min (sample no. 1). Magnified image is shown in the upper inset. (b) Nanoparticle composed of three-variant domains formed after annealing at 873 K for 10 h (sample no. 2).
