X-ray fluorescence holographic study on a room-temperature ferromagnetic semiconductor film of ZnSnAs:Mn was performed using a strong X-ray beam of third generation synchrotron radiation of SPring-8. The real space reconstructions of the environments around Mn atoms were successfully visualized from the observed holograms despite the very small amount of Mn atoms. The reconstructions revealed that the Mn atomsoccupy the cation (Zn or Sn) site.
