| Summary: | In the paper, spin waves in an arbitrary translational-symmetry composite nanosystem containing an “easy axis” ferromagnet are studied. For such a system, equation for the magnetic potential in magnetostatic approximation is obtained taking into account the magnetic dipole-dipole interaction, the exchange interactionб and the anisotropy effects. The theory that allows to obtain the dispersion relation and the transverse wavenumber spectrum for a particular system of this type is proposed; dispersion relation for a system with small transverse size is obtained. The dispersion relation and the transverse wavenumber spectrum are written for nanotubes with round and elliptic cross-sections. |
