## Electrodynamics of Continuous MediaCovers the theory of electromagnetic fields in matter, and the theory of 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. |

Differentiating equation (25.4) with

**respect**to <p and using (25.7), we find thatd2a/8(p2 < 0. (25.8) This means that the point where d<x/8<p = - a = 0 is a

maximum of a as a function of <f>. §26. Thermoelectric phenomena The

The first terms in such an expansion are <D = <D0(Z.) + BM2 + D(l - M)2 - tfM2 - ^

yL2l2 + CL(Mxly - M,lx), (50.1) where <D0 (L) is a function isotropic with

to L. The first two terms (after <D0) are of exchange origin; here B > 0 (otherwise,
