Bifurcations in the Model of a Three-layered Magnetic Structure

On the basis of qualitative analysis of the dynamical system consisting of two coupled Landau-Lifshits equations in nonexchange approximation, the classification of stationary states of three-layered magnetic structure is performed. It was found numerically that at some combinations of the parameters, the phase portrait of the system is featured with limiting cycles that indicates the precession of the magnetic torque in the structure. Before the system will reach the stable parallel-spin confuguration, it passes through a cascade of bifurcations with different types of spin dynamics.
