Ferromagnetic materials are essential parts of modern technology such ashard-disc memory devices and the theory has been studied by numerousphysicists for a long time. This seminar introduces the Landau-Lifshitzequation modeling magnetic vector of ferromagnetic materials and thephenomena called magnetic domain wall from mathematical point of view.The special emphasis is placed on the stationary solution called Blochwall and traveling wave solution called Walker wall.
