Abstract

Thermomagnetic transport parameters have been measured in bismuth at 80 °K and found to be strongly pressure‐dependent. Results indicate that in addition to a decrease in the energy overlap, E~0~, 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 to changes in hole mobility. In some orientations the Seebeck voltage in a field of 0.47 Wb/m^2^ can change sign under uniaxial compression.
