| Abstract: | The temperature dependences of the X-ray absorption spectra (XAS) and of the spectra of X-ray magnetic circular dichroism (XMCD) are measured near the L 3,2 absorption edges of Co and Fe in ludwigite Co2FeBO5 single crystals. The antiparallel orientation of the magnetic moments of cobalt and iron is demonstrated. The coercive fields related to cobalt and iron ions are determined. The orbital (m l ) and (m s ) spin contributions to the total magnetic moments of cobalt and iron ions are identified. The ratios and relative directions of m l and m s are found. |
