Abstract

The original magnetothermal experiments of Kunzler et al. 1 measured slowly varying temperature changes of a thermally isolated sample of bismuth at 4He temperature as the magnetic field was adiabatically varied. An oscillatory variation of the temperature was observed as Landau levels passed through the Fermi surface. As an experimental technique for studying Fermi surfaces, this type of measurement is seriously impaired by extraneous heat inputs to the sample, such as those resulting from mechanical vibrations, fluctuations in the bath temperature, and induced eddy currents in the sample itself. While eddy current heating is not a major problem in bismuth because of its relatively high resistivity, it could easily mask magnetothermal phenomena in higher conductivity metals.
