AgPt NPs after annealing at 400 °C. a STEM-HAADF image; b a zoom on one NP oriented along the [01\(\bar 1\)] zone axis showing the L11 phase with alternating planes of Ag and Pt and its corresponding FFT showing the superstructure reflections. c, d Simulated STEM-HAADF images along the [01\(\bar 1\)] zone axis for an L11 structure and a random solid solution respectively. e–g show multidomains, twin and a stacking fault for L11 NPs (Pt atoms are in red and Ag atoms in grey). The scale is the same for b–g. NP nanoparticle, FFT fast Fourier Ttransform, STEM-HAADF high angle annular dark field in scanning transmission electron microscope
