Abstract:
We consider the dynamics of the magnetization vectors of layers due to the non-linear exchange interaction in layered anisotropic magnetic systems. Particular attention is paid to the stationary states and bifurcation transitions between them, depending on the ratio between the biquadratic and bilinear exchange interaction of magnetic layers in the system based on the model of coupled rotators. It is shown that the experimentally observed parallel and noncollinear ordering of the magnetization vectors of layers and the characteristics of the magnetizations of layers of switching processes from one equilibrium configuration to another can be regarded as a consequence of the bifurcation behavior of the system. The influence of dissipation and the precession of the magnetization vectors in the modes of magnetization reversal in layered magnetic systems is analyzed.
