Abstract: A three-dimensional image of the local neighbourhood of Mn atoms in a Ga_1-xMn_xAs (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.

Keywords: GaMnAs layer; X-ray holography; diffuse scattering.
