Abstract: The mechanical alloying is used to synthesize the amorphous powder of the nominal composition Al65Cr10Fe10Ge15. On the basis of DTA studies, the compound is heat treated at 530 K. The X-ray diffraction of the heat treated phase can be indexed to icosahedral indices. The magnetic susceptibility measurement particularly exhibits some interesting features. A qualitative explanation based on the competition between on-site Coulomb repulsion, which favours local moment formation and the s-d interaction that leads to itinerancy, is attempted which is found to be well correlated with the structural disorder in the system.
