摘要：

Spectrum and damping of spin waves are studied theoretically for the model of periodic multilayer structure with randomly modulated period. It is shown that the energy gap in the spectrum, which is characteristic for periodical structures, transforms into an inflexion of the dispersion curve with increasing random modulation. The results are compared with spin-wave resonance experimental data.
