Effects of nonuniform Mn distribution in (Ga,Mn)As

Ulfat, I. ; Kanski, J. ; Ilver, L. ; Sadowski, Janusz LU ; Karlsson, K. ; Ernst, A. and Sandratskii, L. (2014) In Physical Review B (Condensed Matter and Materials Physics) 89(4).
Abstract
Resonant in situ photoemission from Mn 3d states in Ga1-xMnxAs is reported for Mn concentrations down to the very dilute level of 0.1%. 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. Effects of direct Mn-Mn interaction are found for concentrations as low as 2.5%, and are ascribed to statistical (nonuniform) distribution of Mn atoms.
