Fig. 3. Thermoelectric phase shifts and magnetic flux at different heater currents and hot contact temperatures.

(A) The values of ΔB_n,k versus p at different k and n values close to the line ΔB_n,k = 0 in Fig. 2E with Λ effect excluded. (B) The measured thermoelectric flux values at different hot spot temperatures for two samples with opposite direction of the temperature gradient (symbols). Curves are theory predictions according to Eq. 2.
