(color online) (a) Unit cell structure and spin arrangement of tetragonal CuMnAs, with Mn (purple), Cu (blue), and As (orange) (from Ref. [40]). (b) Registry of the CuMnAs with a III–V semiconductor substrate (from Ref. [40]). (c) X-ray 2θω scans (main figure) and reciprocal space maps (inset) of the CuMnAs(003) diffraction peak for layers on GaP and GaAs (from Ref. [40]). (d) Z-contrast scanning transmission electron microscopy image for the (100) plane of CuMnAs on GaP(001) (from Ref. [3]). (e), (f) 10- field-of-view x-ray photoemission electron microscopy images of antiferromagnetic domains in (e) 80-nm CuMnAs on GaAs(001) (adapted from Ref. [4]) and (f) 45-nm CuMnAs on GaP(001) (adapted from Ref. [7]).
