Thermomagnetic phenomena are considered in a semiconductor crystal having cubic symmetry and an arbitrary relation between energy and wave‐number. The theory is formulated in terms of three basic transport tensors. Expressions are obtained for thermomagnetic effects in the limiting cases of weak and strong magnetic fields. The influence of anisotropy and non‐parabolicity of the energy bands is considered. The results apply both to the manyellipsoid cubic energy bands of Si and Ge and to the non‐parabolic band structure of III‐V compounds.
