• X-ray fluorescence holography (XFH) was applied at the beamline BL37XU of SPring-8 to visualize the three-dimensional local structure around the Mn atoms in a diluted magnetic semiconductor Zn0.4Mn0.6Te. The sample was irradiated by X-rays of certain energies beyond the Mn K absorption edge in order to obtain the Mn Kα fluorescence hologram. A three-dimensional atomic image around the Mn central atoms was derived from the hologram using Barton's algorithm. The nearest- and third-nearest-neighbor Te atoms were clearly visualized. However, the second-nearest-neighbor Zn or Mn atoms are barely visible in this image due to the small scattering efficiencies of these atoms.
