On the Phonon Drag Effect Contribution to Thermomagnetic Phenomena

Calculations are made of the acoustic and optical phonon drag effect contributions to some of the isothermal thermomagnetic coefficients. The scattering is considered to be a mixture of acoustic, optical, and ionized impurity scattering. It is found that the optical phonon drag is of more importance for the thermomagnetic effects than for the thermoelectric effects.
