(a) The magnetization profile of a wide head-to-head DW (solid line). The numerical SW solution (circles) for frequency ! in a linear ferromagnetic chain cannot be distinguished from the solution (dashed line) for the continuum model. (b) A computed narrow DW profile (triangles) compared with the Walker model (squares). The SW amplitude for a selected frequency is shown by circles. (c) The ground state profile of an abrupt DW (triangles) compared with the Walker profile (squares). The amplitude of a SW for another given frequency is shown by circles.
