To search the atomic sites of Mn impurities in Bi{sub 2}Te{sub 3}Mn{sub 0.1} topological insulator, a Mn Kα fluorescence x-ray holography experiment was performed. The reconstructed atomic image around the central Mn atom reveals a hexagonal configuration, where the local lattice constant is slightly larger than the original Bi{sub 2}Te{sub 3} crystal. Thus, the most plausible atomic position of Mn impurities is the substitution with Bi or Te atom. The further-distant atomic images are hardly observed unlike usual crystals, indicating a formation of flat clusters around Mn in this functional crystal.
