Magnetic Properties of Liquid Pd, Si, and Pd-Si Alloys

The magnetic susceptibility χ of liquid Pd, Si, and Pd-Si alloys was measured. For crystalline semiconducting Si, χ changes at the melting point TM from diamagnetic to paramagnetic values in good agreement with existing theoretical calculations for the liquid state. For liquid Pd, χ is discussed within the Stoner-Wohlfarth and Edwards models. The data obtained for liquid Pd-Si alloys provide an understanding of the diamagnetism of the metallic glass Pd₈₁{Si}₁₉$ and will be discussed in the light of recent density-of-states data obtained by photoemission.
