Local atomic structure around Ge atoms in Ge$$_{1-x}$$Mn$$_{x}$$Te thin film single crystal has been investigated by X-ray fluorescence holography (XFH) at room temperature. Obtained atomic image suggests that the Ge position is not stable in the exact positions of the anion fcc sublattice of the anion, and reveals the fluctuation of the Ge positions or the existence of cation vacancies.

The local atomic structure around Mn atoms in Ge$$_{1-x}$$Mn$$_{x}$$Te thin-film single crystal has been investigated by X-ray fluorescence holography (XFH) at room temperature. The obtained atomic image suggests that the Mn atoms replace the Ge atoms in the host GeTe, and the Mn position is stable in the exact positions of the anion fcc sublattice. The XFH result also suggests the fluctuation of the Ge positions or the cation vacancies.
