Title: Stability of traveling domain walls in three dimensions

Time&Venue: 2025.05.30(星期五) 15:00-16:00&南楼N702

Abstract: In this talk, we address the stability of a traveling magnetic domain wall, first derived by Walker in 1956, within the three-dimensional Landau-Lifshitz-Gilbert model describing ferromagnetic materials subjected to an external magnetic field. We establish that the Walker domain wall configuration remains stable provided the external magnetic field and the anisotropy field are sufficiently weak, and the Gilbert damping parameter is appropriately large.
