Self-modulation of dipole-exchange magnetostatic waves in coupled ferromagnetic structure with perpendicular magnetization
The basic features of development of magnetostatic waves self-modulation processes in double-layer ferromagnetic structure are numerically studied in framework of system of the one-dimensional nonlinear nonstationary Schrodinger equations. The estimation of influence of coupling between films on group velocities, dispersion and nonlinearity coefficients was carried out taking into account the exchange interaction. The use of different types of excitations of coupled structure and change the value of coupling between films enables both to adjust frequency of MSW self-modulation, and to observe change of character of wave evolution in direction from order to chaos, and from chaos to order.
