Structural characterization of the diluted magnetic semiconductor CuGa<inf>(1-X)</inf>Mn<inf>(X)</inf>Se<inf>2</inf>

Abstract:

The crystal structure of the diluted magnetic compounds CuGa(1-X)Mn(X)Se2, x = 0.1, 0.3, 0.5, were characterized using X-ray powder diffraction data. All compounds crystallize in the tetragonal space group I 4 2d (N° 122), with a chalcopyrite-type structure. In all alloys, Mn-substituted of I-III-VI2 chalcopyrites, the Mn cation preferred the Ga site which supports its ferromagnetic properties. These results are consistent with the first-principles calculations reported so far.
