Thermoelectric power of Ni-Zr metal glasses

We have measured the thermopower of Ni-Zr metallic glasses over the range of composition from ${\mathrm{Ni}}_{70}$ ${\mathrm{Zr}}_{30}$ to ${\mathrm{Ni}}_{25}$ ${\mathrm{Zr}}_{75}$. In contrast to the other simple nonmagnetic metallic glasses, Mg-Zn and Cu-Zr, the thermopower is a strong function of composition and changes sign at the Ni-rich end. The results are shown to be consistent with the Faber-Ziman model for liquid metals.
