Thermopower of the YbIn(1-x)AgxCu4 alloy system: what does the thermopower minimum reflect in YbIn(l-x)AgxCu4?

We have found that the temperature of the thermopower minimum Tm, in the YbIn1-xAgxCu4 alloy system shows the same concentration dependence as the Kondo temperature extracted from susceptibility data, TKS. However, the temperatures Tm are, on average, about four times smaller than these Kondo temper...

Description
Summary:We have found that the temperature of the thermopower minimum Tm, in the YbIn1-xAgxCu4 alloy system shows the same concentration dependence as the Kondo temperature extracted from susceptibility data, TKS. However, the temperatures Tm are, on average, about four times smaller than these Kondo temperatures TKS. We discuss the origin of the thermopower minima and suggest possible interpretations of the extracted parameters Tm and TKS from experimental data.
