| Abstract: | The axial and radial magnetic domain wall distributions of cylindrical multilayer nanowires were analytically studied using the method of micromagnetics.In the case of axial symmetry,the analytical solutions of Euler equation for the radial domain wall were obtained by appropriate changing of the form of the anisotropy energy of the cylindrical multilayer nanowires.Numerical calculations show that this analytical solution can give a reasonable distribution of domain wall. |
