Abstract
The thermoelectric power of a number of magnetic and nonmagnetic amorphous metallic alloys has been measured as a function of temperature between 15 and 580 K. The temperature dependence of the thermopower for the magnetic alloys is qualitatively different from that for the nonmagnetic alloys. The data for the nonmagnetic alloys are consistent with the extended Ziman theory for transport in liquid and amorphous metals. It is argued that the data for the magnetic alloys are consistent with a model, based on the Kondo scattering of conduction electrons by spins situated in low internal fields, which was recently proposed to explain the resistivity minima observed in these materials.
