Chapter 7 Thermomagnetic effects and measurements

The thermoelectric and thermomagnetic transport properties of solid state systems are typically used as research tools to explore electron and phonon behavior within the material and as a measure of the usefulness of the material for potential applications. The magnetic field and temperature dependence of the transport effects determine the performance of the material for electronic refrigeration, govern materials optimization efforts, and expose the underlying physical transport mechanism of the material, including effects associated with carrier concentration, mobility, and scattering mechanisms. The particular complications associated with thermomagnetic transport effects have been reviewed, proper methods of measuring these transport coefficients have been discussed, and the transport properties of an idealized thermomagnetic electronic refrigeration material have been given.
