Investigation of Transport Coefficients in Semimetals by the Variational Method III. Commutational Effect of Magnetothermo‐E.M.F. in Bismuth

Abstract

The possibility of the commutational effect (CE) of thermo-e.m.f. a t different orientations of the magnetic field and temperature gradient is investigated in the frames of the variational method of calculation of transport coefficients. It is found that for some of the components of the magnetothermo-e.m.f. tensor CE appears only in strong and intermediate fields.

Galvanomagnetic Effects of Bismuth in Non‐Quantising Magnetic Fields. Pseudo‐Parabolic Model

“…For the range of classical magnetic fields and the temperatures considered the transport properties are reasonably well accounted for, both in the pseudo-parabolic model and in the work by Gitsu et al [5]. However, some basic problems remain.…”

“…For this reason we want in the present communication to report on the galvanoinagnetic properties as found from the pseudo-parabolic model and the pseudo-parabolic Fermi energy. Further we want to comment on the papers by Gitsu et al [5].…”

“…I n order to obtain these elements, also elements of the resistivity tensor were calculated; but these latter elements were not reported, as they are less informative as regards the energy dependence of the scattering rate. Recently, however, Gitsu et al [5] have published a series of papers reporting very comprehensive theoretical work and numerical results on the thernioinagnetic as well as the galvanomagnetic properties. The method used by Gitsu et al, and also the type of input parameters, differs in several essential ways from [3].…”
