Abstract
The results of measurements of the thermopower S(T), thermal conductivity κ(T), and Hall coefficient R_H(T) of CeRhIn are presented in order to correlate the behaviour in these properties with the previously reported intermediate-valent-related phenomena. Extrema are found in both S(T) and κ(T) near the susceptibility-derived Ce³⁺ → Ce⁴⁺ excitation temperature of T_ex~= 133 K. The Hall coefficient is found to be small and positive, suggesting a metallic-like carrier concentration.
