Interconfigurational Fluctuations in the Dilute Magnetic Alloy and Thermopower Measurements
A new theoretical treatment of the dilute alloy problem which begins by treating the impurity correlation problem exactly is briefly discussed. The central result of the theory is the inter-configurational excitation energies of the impurity acquiring a temperature dependent shift through their coupling to the conduction electron gas. This shift induces a characteristic behavior in the low temperature S/T values which is confirmed for AuFe and CuFe systems. The need for new low temperature thermopower measurements for families of alloys to test this new theory is emphasized.
