Abstract
Polycrystalline with x=1.2–25 at. % and amorphous ( with x=0–19.3 at. % were prepared. The physical properties measured for these samples included the magnetic moment, the high-field susceptibility, the specific heat, the residual resistivity, and the anisotropic magnetoresistance at low temperatures. We have now more experimental data for alloys to test the prediction of the split-band model. As to ( alloys, the complications of the spin-glass property and the strong increase of resistivity due to s-s scattering make the test very difficult. However, the existence of a maximum in the high-field susceptibility in ( indicates a near degeneracy at the Fermi level, which may or may not be associated with the split-band model.
