A theory is developed for the propagation of spin waves in heterogeneous ferromagnetic systems. The theory provides for the generation of spin waves using a spin-polarized current and control of the process of propagation of spin waves in such media. In particular, the mechanism of excitation of dipole-exchange spin waves in a multilayer ferromagnetic nanosystem is presented.

A theory is developed for the reflection of spin waves from periodic modulated ferromagnetic structures with complex interfaces, taking into account the generalized boundary conditions including the inhomogeneous character of the contact boundaries of two homogeneous media formed as a result of the superposition of crystal lattices of two contacting

The theory was developed of propagation of spin waves in two-sublattice antiferromagnet with uniaxial magnetic anisotropy and ferromagnetic nano-shaped spherical nanoshell, nanoshell of an ellipsoid of rotation form ("nanorise"), cylindrical nanotubes of circular (circular cylinder) and elliptical (elliptical cylinder) section and for arbitrary ferromagnetic nanosystems with transmitting symmetry.
