Abstract : The report is concerned with an investigation of the structure sensitive properties of intermediate solid solutions or intermetallic compounds NiAl, CoAl, NiGa, and CoGa. The optical properties of the beta' phases of NiAl, NiGa, CoAl and CoGa indicate that some of these alloys show free-electron behavior below photon energies of about 1 eV. The electrical resistivity of the four beta'-alloys indicate that the alloys are metallic but not good conductors. (Author)
