Electrical resistivity of polycrystalline scandium has been studied between 1.38 and 358.8 deg K. The measurements show a step-type anomaly in the resistivity between 4 and 5 deg K and possibly a very small minimum at 9.5 deg K. Considerable hysteresis in the electrical resistivity exists at low temperatures, depending upon the previous thermal history of the sample. It is very likely that these anomalies may be associated with a superconductive substructure resulting from the presence of small amounts of tantalum as an impurity. However, the possibility that the anomalous behavior is due to the occurrence of some cooperative magnetic states at low temperatures cannot be completely eliminated at the present time. Between about 80 and 380 deg K the intrinsic resistivity of scandium is describable by the Bloch-Gruneisen formula with Debye theta of 275 deg K. At lower temperatures the temperature dependence of the intrinsic reaistivity is consistent with expectations derived from the irterband electron-phonon scattering. Ziman's reduced electrical resistivity at 300 deg K is calculated to be 50.8. (auth)
