1s2p RIXS–XMCD on Fe3O4 in the pre-edge region of the K-edge. Upper left: Fe Kα1 intensity as a function of incident energy for left and right circularly polarized light (LCP and RCP) with the sample magnetized along the incident X-ray direction in a field of 0.7 T. Bottom left: the difference between RCP and LCP Fe Kα1 intensity as a function of incident X-ray energy for the two magnetic field directions. Right: the RIXS–MCD map showing the dramatic magnetic contrast for RCP–LCP in a magnetic field of 0.7 T. |
