The differential equations and boundary conditions describing the behavior of a finitely deformable, polarizable and magnetizable, heat conducting continuum in interaction with the electromagnetic field are derived by means of a systematic application of the laws of continuum physics to a well-defined macroscopic model. The model consists of an electronic charge and spin continuum coupled to a lattice continuum, which in itself consists of two interpenetrating ionic continua, which can displace with respect to each other to produce ionic polarization. As spin angular momentum and electronic and ionic linear momentum are taken into account, magnetic spin resonance and both ionic and electronic polarization resonances are included in the treatment. Magnetic interaction terms are obtained by regarding magnetization as a consequence of point circulating current densities. When material resonances are suppressed, a simpler model is applicable and a not only smaller but somewhat different system of equations turns out to be convenient. Author
