A lot of efforts have been recently concentrated on investigation of ferromagnetic semiconductors due to their potential application for spintronic devices . Ferromagnetic GaMnAs is one of materials most interesting for these purposes. The lattice parameter of Ga1-xMnxAs (aL) increases linearly with the Mn content up to x about 0.1. However, different scientific groups (e.g. ) presented rather non-consistent data concerning the aL value dependence on the Mn content. It has been reported, that these discrepancies are due to the presence of different defects, namely of manganese interstitials and arsenic antisites in GaMnAs .
