Abstract

The adiabatic Nernst-Ettingshausen, thermoelectric, and thermal transverse-even coefficients are measured in magnetic fields to 3.3 T (33 kG) in the (001) rotation plane, and at temperatures between 1.2 and 4.2°K in metallic tin. The results demonstrate the effects of Fermi-surface topology on the Nernst-Ettingshausen coefficient. By assuming the validity of the Wiedemann-Franz law, the temperature and field dependences of the adiabatic thermomagnetic coefficients are predicted from a theory for the isothermal coefficients. These predictions are compared with experiment. Strong quantum oscillations in the thermoelectric power are discussed and compared with theory.
