摘要

Granular GaAs:(Mn,Ga)As films were prepared by annealing the Ga_(0.92)Mn_(0.08)As/GaAs layer grown by the MBE method at low temperature. The annealing was performed at 500 or 600 8C. It is commonly accepted that this processing should result in formation of cubic zinc blende or hexagonal MnAs inclusions depending on the temperature. We demonstrate that such a priory assumption is not justified. The kind of formed inclusions depends not only on the annealing temperature but also on the number of defects andMnatoms in the substitutional and interstitial positions in as grown sample.
