The thermoelectric power of a number of magnetic and nonmagnetic metallic glasses has been measured as a function of temperature between 15 K 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 and show positive values for thermopower, Q, when the temperature coefficient of resistivity, α, is negative and negative values for Q when α is positive. The data for the magnetic alloys are consistent with a model based on the Kondo scattering of conduction electrons by spins situated in low effective fields.
