The book discusses the theory of ferromagnetic resonance in detail and the investigations and treatments of problems in this theory. The text consists of nine chapters covering such topics as the linear approximation of ferromagnetic resonance; non-linear processes occurring during ferromagnetic resonance in ferromagnetic semiconductor; the spin-wave theory of ferro- and antiferromagnetism and its application to the problem of ferromagnetic resonance; and the theory of the line width of the resonance absorption of the energy of a UHF field in ferromagnetics. Physicists will find the book very useful.
