The goal of this article is to analyse the time asymptotic stability of one dimensional Bloch wall in ferromagnetic materials. The equation involved in modelling such materials is the Landau-Lifschitz system which is non-linear and parabolic. We demonstrate that the equilibrium states called Bloch walls are asymptotically stable modulo a rotation translation transverse to the wall. The linear part of the perturbed equation admits zero as an eigenvalue forbiding a direct proof.< Leer menos
