Thermomagnetic effects in cadmium arsenide

Abstract
Adiabatic and isothermal thermomagnetic coefficients have been obtained for cadmium arsenide in the temperature range 65-300°K. By assuming acoustic scattering and a single parabolic conduction band model, agreement between experiment and theory has been demonstrated over most of the temperature range, but results indicate the presence of mixed acoustic and impurity scattering at the lower temperatures. However, the measured values of thermal conductivity cannot be entirely explained as a function of temperature since there is an anomalous increase at higher temperatures.
