Thermoelectric power of noble-metal spin-glass alloys

Abstract

We report experimental data for the thermoelectric power of noble-metal spin glasses and analyse them in terms of the spin-glass excitation spectrum computed by Walker and Walstedt in 1980, along the same lines, and with the same values of T*, as in the work of Campbell, Ford and Hamzitć in 1982 for the resistivity. Reasonably good fits to the data are obtained; the absence of a sign change in the thermopower of Au-Fe is also discussed.
