β¦ Synopsis
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.

Investigations on heat conductivity and electrical resistivity of tungsten single crystals were started in 1936 with measurements on two tl~n crystals. Results on these crystals are given in this paper. Using a single crystal with its a:ds parallel to the (1, 1, 1)direction, we failed in sepm'ating
A discussion is given of the considerations of Meixner and Koh-1 e r according to which the change of resistance in a magnetic field is not necessarily an even function of the field strength: it may contain odd powers of H andeven a linear term. No experimental evidence for the existence of such ter
