Hall coefficient of technically pure metals from 80 °K to 800°K
Tóm tắt
The Hall coefficients of Cu, Ag and Au are very similar in their temperature dependence, exhibiting (numerically) a flat minimum at ca. 200°K, a slow rise at high temperatures and a more rapid rise at low temperatures. The variation is within 10-15% of the room temperature value, which is 3 to 5 times the variation caused by thermal expansion on the basis of a one-band model. For Pd and Pt a sharp minimum is found, and the variation on the high temperature side is strong (at variance with older work for Pt). This is tentatively ascribed to a thermal shift of the Fermi surface, possible in view of the low degeneracy temperature of these metals.
