MAGNETIC-SUSCEPTIBILITY OF LIQUID GE-SE ALLOYS

The dependence of magnetic susceptibility on composition for liquid Ge 1-cSec alloys exhibits a broad minimum around the composition c = 0.72 in the temperature range of 1023-1223 K. At higher temperatures, the broad minimum moves to the composition c = 0.5. The exponential temper ature dependence of paramagnetic susceptibility on the Se-rich side ca n be explained by the formation of the Curie-like spin states. The mov ement of broad minimum is caused by a rapid increase in the Curie-like spin states with increasing temperature. The paramagnetic susceptibil ity on the Ge-rich side depends mainly on the density of states at the Fermi level.
