Abstract: | The specific heat and magnetic susceptibility of the transition metal oxide ReO3 have been measured. The specific heat results give a Debye temperature ΘD = 460 ± 10 K and an electronic specific heat coefficient γ = 6.45 ± 0.07 cal/mole K2 which are in good agreement with similar measurements on the cubic sodium tungsten bronzes. The magnetic susceptibility and the electronic contribution to the specific heat are within a few percent of the corresponding parameters calculated from the free electron model with one electron per unit cell. Our results show that ReO3 behaves much like a simple metal. No experimental evidence for narrow d-band effects was observed. |
