Abstract

The Mg2SixGe1-x solid solution was prepared by heating stoichiometric amounts of elemental Mg, Si, and Ge in an argon atmosphere. Both microprobe and X-ray diffraction analysis of the reaction products suggest that homogeneous alloys can be made by heating the elements to 1200 °C, a temperature roughly 100 °C in excess of the melting temperatures for pure Mg2Si and Mg2Ge. 29Si solid-state nuclear magnetic resonance was used to characterize the Mg2SixGe1-x solid solution. The 29Si isotropic chemical shift changes consistent with the band gap in these materials while the line width increases with local disorder.
