Rotation of the staggered AF moments due to exchange coupling, and anisotropic XMLD spectra. (a) Experimental geometry for the XMLD measurements. (b) Fe L 2,3 and (c) Mn L 2,3 XMLD spectra, obtained as the difference between absorption spectra measured with x-ray linear polarization vector along the [110] and \([1\bar{1}0]\) directions of the GaP substrate, with applied magnetic field along [110] (thick lines) and along \([1\bar{1}0]\) (thin lines). The inset to (c) shows the magnitude of the Mn L 3 XMLD peak as a function of temperature. (d) Fe L 2,3 and (e) Mn L 2,3 anisotropic XMLD spectra, obtained from the difference between absorption spectra with parallel and perpendicular configurations of the x-ray polarization and the 1000 Oe applied magnetic field, for fields along 〈110〉 (thin blue lines) and 〈100〉 (thick red lines) in-plane axes. The experimental XMLD spectra in (be) are measured at temperature T = 250 K. (f) Calculated Mn L 2,3 anisotropic XMLD spectra for tetragonal CuMnAs.
