Crystal structure, magnetometry and XMCD. (a) Crystal structure of tetragonal CuMnAs. (b) and (c) SQUID hysteresis loops for the Fe/CuMnAs film at 200 K and 2 K respectively, for magnetic field along the substrate [110] (filled symbols) and [100] (open symbols) axes. (d) Experimental geometry for the XMCD measurements. (e) Fe L 2,3 and (f) Mn L 2,3 absorption spectra for magnetic fields applied parallel and antiparallel to the x-ray helicity vector, and the difference (XMCD) spectra, at sample temperature 250 K. The Mn XMCD is scaled by a factor of 10 for clarity.
