“…NdOs 4 P 12 and GdOs 4 P 12 show a ferromagnetic transition at 1.15 K and 5 K, respectively. 19,20) S (T ) of PrOs 4 P 12 at room temperature is 12.7 µV/K and reduces on cooling below 150 K. The curvature of S (T ) in all compounds becomes large around 100-130 K. One possible explanations for this is the proximity to Θ D /5, i.e., the expected phonon drag peak taking into account the reported value of Θ D = 523 K for Ln = La. For PrOs 4 P 12 , the behavior of S (T ) is different from that for LaOs 4 P 12 .…”

We report the specific heat and thermoelectric power S (T ) of filled skutterudite PrOs 4 P 12 , which has a Γ 1 crystalline electric field ground state. The electronic specific heat coefficient γ of PrOs 4 P 12 indicates a weak enhanced value (γ Pr /γ La ∼ 2.3) in comparison with that of LaOs 4 P 12 . The influence in the specific heat by c-f hybridization effect is discussed. S (T ) of PrOs 4 P 12 exhibits a small maximum around 10 K although there is no such maximum for LnOs 4 P 12 (Ln = La, Nd, and Gd). Consequently, S /T for Ln = Pr increases below 20 K, which is consistent with the enhanced γ. We also report the magnetization process to 46 T in PrOs 4 P 12 .
