An X-ray fluorescence holography (XFH) measurement was performed at the beamline BL-3A in the Photon Factory to visualize the three-dimensional local atomic image around the Zn atoms in a diluted magnetic semiconductor Zn0.4Mn0.6Te. The nearest- and third-nearest-neighbor Te atoms were clearly visualized. The second-nearest-neighbor Zn or Mn atoms were, however, barely visible, although they could be seen in the reference ZnTe crystal. This result is similar to the previous Mn Kα XFH data, and may suggest a rigid Te sublattice and a highly distorted cation sublattice, which contradicts a structural model for a similar diluted magnetic semiconductor Cd1-xMnxTe by Balzarotti et al.
