Effects of nonuniform Mn distribution in (Ga,Mn)As
Copyright policy )Effects of nonuniform Mn distribution in (Ga,Mn)As
Resonant in situ photoemission from Mn 3d states in Ga_{1-x}Mn_{x}As is reported for Mn concentrations down to very dilute limit of 0.1 at %. The properties of the peak at the valence-band maximum reveal an effective interaction between Mn 3d states for concentration as low as 2.5 %. Concentration-dependent spectral features are analyzed on the basis of first-principles calculations for systems with selected impurity positions as well as for random alloys.
