Transverse galvanomagnetic and thermomagnetic coefficients of a molybdenum single crystal

With the magnetic field aligned along [100] and the current along [110], the following transport coefficients have been determined: the transverse and Hall electrical resistivities, the transverse and Righi-Leduc thermal resistivities, and the Nernst-Ettingshausen coefficient. If the transverse electrical resistivity is represented as Bⁿ (B is the magnetic field), then n is found to peak at about 1.90 as B increases, and steadily decline at higher fields. The lattice thermal conductivity is extracted from the data by two methods, the results of which are not identical but are within experimental uncertainty. The Nernst-Ettingshausen coefficient yields a density of electronic states consistent with that derived from specific-heat work, in agreement with recent theoretical predictions.
