Thermopower of cadmium and tungsten single crystals in a magnetic field

Abstract

The thermopowers of single crystals of Cd and W have been measured between 1.5 and 4 K in a magnetic field, directed along high symmetry axes. Care has to be taken in the elimination of probe misalignment effects. The thermopower results are consistent with experimental values for electrical and thermal resistivity tensor elements which occur in the equation for the thermopower in a high magnetic field. However, the apparent departure from the expected field dependence of pxy has led us to question current theory.
