The Role of Interstitial Mn in GaAs-Based Dilute Magnetic Semiconductors,cations. For the latter, however, the temperature of the transition to the ferromagnetic phase has to be considerable increased. In the reported studies it was shown that the limit for such an increase is imposed by the presence of Mn ions in the interstitial positions (MnI).
