Fig. 2: Characterization and structural analysis of RuIrFeCoCrO2.

TEM (a), XRD (b), and AFM images (c) of RuIrFeCoCrO2. d, e Aberration-corrected HAADF-STEM images. The inset in (d) is the corresponding SAED image. The red dots in (e) indicate the metal atoms. f Line-scanning intensity profiles obtained from the atomic arrangements highlighted with yellow and blue boxes. g GPA analysis for strain distribution. The red and blue areas present tensile and compressive strain (εxx), respectively, along the x direction. h, i HAADF-STEM image and elemental mappings.
