Electrons in solids behave like microscopic bar magnets, and in certain solids these align to produce macroscopic magnetizations. This book deals with the dynamics of this magnetization field, which is intrinsically nonlinear. This is important in applications, particularly magnetic recording, which involves very large motion of the magnetization, well beyond the validity of linearized (small motion) approximations or their limited extensions. The author therefore emphasizes nonlinear solution methods but with only minimal use of numerical simulation. The book should be useful to physicists studying magnetic phenomena.
