title = "Formation of Mn-As centers in In1-xMnxAs diluted magnetic semiconductors",
abstract = "XAFS spectra at the Mn K-edge were obtained for films of In1-xMnxAs (0.0014≤x≤0.12) grown by MBE method at two different substrate temperatures Ts = 200-210 °C and Ts = 280-300 °C. It has been found that Mn-As complexes which consist of a central Mn atom surrounded by six neighboring As most likely arranged in the form of a distorted trigonal antiprism with one or two additional Mn atoms placed on the long axis of the antiprism, can substitute for the In-As tetrahedron in the undistorted zincblende structure. For a composition of x = 0.12 we have found the formation of MnAs clusters with NiAs-like structure in the high-growth-temperature samples. We thus conclude that the magnetic properties of the In1-xMnxAs semiconductors are mainly determined by the formation and local structure of the Mn-As complexes.",
