Some features of the transverse thermomagnetic effect in bismuth

The transverse Nernst‐Ettingshausen (N‐E) effect in Bi samples with different crystallographic orientation is discussed. It is found that in samples in which the temperature gradient is directed along one of the basic crystallographic directions (bisector, C2 or C3) and a non‐zero component of the magnetic field along the C2‐axis (which is assumed to be the X‐axis) is present, the value comprises mixed even terms. It is shown that the conditions for even terms in transverse N‐E effect are identical with those for odd terms in longitudinal N‐E effect [2].
