Computer simulation of magnetization dynamics in a two-layer ferromagnetic structure
The paper considers the use of a mathematical software package for modeling the nonlinear precession of magnetization in a two-layer film. The solution of a system of differential equations describing the motion of the magnetization vectors was obtained using numerical methods. Precessional portraits are constructed at orientation transitions of oscillations of the magnetization vectors in the case of the presence of a field of cubic anisotropy and the symmetric action of the fields on the film.
