摘要：
ESR of Mn-doped GaAs is studied. The results indicate the presence of an interstitial impurity state in GaAs:Mn which is involved in the Coulomb interaction with the substitutional Mn states. Analysis of the temperature variations of ESR spectra and the values of the g factor shows that the interstitial center has a d5 electron configuration. The substitutional Mn create a strong random crystal field at the interstitial Mn ion. The results can be explained by assuming the existence of a nonzero dipole moment in the neutral state of Mn.
