Figure 1
Images acquired at 721.5 eV (A) and 723.2 eV (B) at the Fe L₂ edge using linearly polarized X-rays show the antiferromagnetic domain structure of LaFeO₃. The domain contrast at energy B is reversed compared with that at A. In the divided image B/A, referred to as the XLMD image, contrast of non-magnetic origin (topography, chemical composition) is suppressed. Local spectra measured within a dark and a bright domain show the origin of the image contrast: the branching ratio between two multiplet peaks at the L₂ edge changes, because of the different angle between the X-ray polarization vector and the antiferromagnetic axis in each domain. The measurement geometry is also shown.
