Magnetism and the stability of (Ga1-xFe x )As are investigated using the first principles LMTO-ASA band calculation by assuming supercell structures.Four concentrations of the 3d impurities are studied ( x =1,1/2,1/4,and 1/8).The results show the effect of varying Fe concentration on the magnetic and stable properties.
