On the stability of Bloch walls in a dynamical model with eddy currents Capella Kort, Antonio


One of the main features of micro magnetic materias is the formation of magnetic domain separated by the so called magnetic walls. These walls are transition layers that move upon the application of external magnetic fields. In bulk material the main type of walls is the Bloch wall. There are two models for micro magnetic precession dynamics with damping. One based in Landau-Lifshitz-Gilbert (LLG) equation and other based on eddy current damping. In this talk we prove some stability results for the Bloch wall under the eddy current damping model and the LLG model.
