Essay

The thesis deals with a research of the influence of relaxation processes on reflection processes of spin waves in two- and multilayer ferromagnetic structures and problem of excitation of nonlinear spin wave. The amplitudes of reflection and transmission of spin waves were defined for uniaxial and tetragonal ferromagnets, complex refraction index and reflection coefficient of spin waves in tetragonal multilayer ferromagnetic structures taking into account spin wave relaxation in form proposed by V.G. Baryakhtar were defined. The transformation of linear wave to nonlinear spin wave in the structure, consisting of two uniaxial ferromagnets was described.
