A three‐dimensional image of the local neighbourhood of Mn atoms in a Ga 1− x Mn x As ( x = 0.02) layer has been obtained by using X‐ray diffuse scattering holography. The first and second nearest neighbours of the Mn atoms correspond to the local structure around Ga atoms in the zinc‐blende GaAs structure. Accordingly, the Mn atoms are situated in substitutional positions.
