Galvanomagnetic and Thermomagnetic Effects in Isotropic Materials

Invariant‐theoretical considerations are employed to obtain constitutive equations for the current density vector, the heat flux vector, and the magnetic intensity field in isotropic materials (both holohedral and hemihedral) when an electric field, a magnetic induction field, and a temperature gradient are simultaneously present in the material. Certain of the interaction effects which are indicated by these constitutive equations are discussed.
