Abstract
The dc resistivity and low-field Hall effect of the transition-metal oxide Re have been measured as a function of temperature. The samples used were oriented single crystals which were large enough for measurements to be made by a conventional four-point probe method. The samples of Re showed metallic conductivity with a resistance ratio between 50 and 70. At 300°K resistivity is (8.95 ± 0.03) × Ω cm, and the Hall coefficient at 300°K is (-3.28 ± 0.10) × . The experimental results show that Re behaves like a simple metal with one free electron per unit cell. A least-squares fitting routine is used to compare the resistivity data to a model involving electron-phonon and electron-electron scattering.
