Figure 5: HAADF images alongside the STEM simulation image and model of the interface.

(a) The surface layer is spinel viewed in [111]S zone axis, while the bulk shows predominantly a single variant of the monoclinic structure. The interface is (010)M. (b,c) Spinel surface on other facets on the same particle, at 120 degrees from (010)M as shown in c but also seen on facets normal to (010)M, as shown in the upper part of the image in c. (d,e) Spinel surface and the bulk in [110] and [010] zone axes, respectively. (f) Surface spinel in [112] zone axis and the bulk in the orientation equivalent to [001]M. Only one variant of the monoclinic structure is shown in the model and STEM simulation. HAADF images in a, b, c and f were recorded from the plate sample, while those in d and e were recorded from the commercial HCMR XLE2 sample.
