## Electrodynamics of continuous mediaCovers the theory of electromagnetic fields in matter, and the theory of the macroscopic electric and magnetic properties of matter. There is a considerable amount of new material particularly on the theory of the magnetic properties of matter and the theory of optical phenomena with new chapters on spatial dispersion and non-linear optics. The chapters on ferromagnetism and antiferromagnetism and on magnetohydrodynamics have been substantially enlarged and eight other chapters have additional sections. |

For this reason the change in direction of the spontaneous

requires only a slight reconstruction of the lattice and can occur quite easily. The

actual nature of the ferroelectric properties of a body depends on its crystal

If we are not interested in the details of the structure, and consider portions of the

body which are large compared with the domains, we can use the

averaged over such portions. Its component Pz can evidently take values in the ...

Hence we see that the wave-vector surface in this case consists of two spheres

with radius n0, whose centres are at distances ąg/2n0 from the origin in the

direction of G. A different
