Thermomagnetic transport parameters have been measured in bismuth a t 80 O K and found to be strongly pressure-dependent. Results indicate that in addition to a decrease in the energy overlap, E,, there is an increased participation of a light hole band increasing the mobility of holes. The Nernst effect and the magneto-Seebeck effect are particularly sensitive t o changes in hole mobility. I n some orientations the Seebeck voltage in a field of 0.47 Wb/m* can change sign under uniaxial compression.I n Wismut wurden bei 80 O K die thermomagnetischen Transportparameter gemessen, und es wurde gefunden, daB sie stark druckabhiingig sind. Die Ergebnisse zeigen, daS zusiitzlich zu einer Verringerung der Energieuberlappung E, eine VergroSerung des Anteils eines Bandes leichter Locher auftritt, was die Beweglichkeit der Locher erhoht. Der Nernsteffekt und der Magneto-Seebeckeffekt sind besonders empfindlich gegeniiber hderungen der Locherbeweglichkeit. Bei einigen Orientierungen kann der Seebeckeffekt in einem Feld von 0,47 Wb/m2 unter einachsigem Druck sein Vorzeichen iindern.

The transverse magnetoresistance anisotropy along the bisectrix axes of Bi and Bi (98)Sb(2) single crystals at 4.2 and 89 K is compared with the theory for magnetic fields applied in two symmetry directions. It is found that the changes in shape of the magnetoresistivity anisotropy curves are consistent with expressions derived from Aubrey's magnetoconductivity tensor for bismuth. L'anisotropie de la magnbtorbsistance transversale le long des axes bissectrices de monocristaux de Bi et de Bi(98) Sb(2) it 4.2 et i 89 K est comparbe Q. la theorie pour des champs magnbtiques appliqubs dans les deux directions de symbtrie. I1 s'avhre que les changements de forme des courbes d'anisotropie de la magnktoksistivitk sont en bon aocord avec les expressions derivkes du tenseur de magn6toconductivit6 pour le bismuth calculk par Aubrey.
