Notes:
Measurements of the Hall coefficient R H have been made as a function of temperature between 4 and 100 K for single-crystal and polycrystal α-U and α-phase U-Mo alloys containing 0.6, 3, and 7 at % Mo. A strong temperature dependence for R H, leading to a change in its sign for the single-crystal sample, is found for the uranium below 45 K. Alloying with Mo reduces the temperature dependence of R H and that for the 7 at % Mo alloy is temperature independent. The anomalous transport behavior for the uranium is linked with the anomalies which have been observed in many of the physical properties of uranium around 45 K, and the possibility that these are due to a change in Fermi surface topology resulting from a periodic lattice distortion associated with charge density wave formation is discussed.
