THE THERMOELECTRIC POWER IN CHROMIUM AND VANADIUM
The thermoelectric power in pure chromium and vanadium was measured between 4.2 and 340 un. Concent 85% K and found to be positive in both metals over the whole temperature range. Maxima in the curves of thermopower against temperature at low temperatures are interpreted in terms of a phonon drag component. An anomaly in the results for both monocrystalline and polycrystalline chromium at the Neel temperature is interpreted in terms of the Lidiard-Overhauser model of conduction electron antiferromagnetism. Hysteresis in the measurements on chromium over the whole temperature range is attributed to the effect of antiferromagnetic domains. An anomaly in the thermopower of vanadium at approximately 217 un. Concent 85% K is attributed either to a transition to an antiferromagnetic state or to a structural phase transition, possibly involving ordering of impurities. Experiments for distinguishing between these possibilities are suggested. (auth)
