Electrical conductivity of liquid Sb and Bi doped with 3d transition metals

The electrical conductivity of liquid Sb and Bi doped with 3d transition metals (Ti, V, Cr, Mn, Fe, Co, Ni, and Cu) was measured. The results demonstrate that small (less than or equal to3 at %) additions of these metals reduce the conductivity of the melts by up to 4%, except for Ni and Cu, which slightly raise the conductivity of liquid Sb. This finding is interpreted in terms of s-d hybridization. The scattering of electrons is considered using the Friedel-Anderson approach, based on the concept of virtual bound states.
