Abstract
A theory of the spectrum of spin waves in partially randomized multilayers is developed. A model of a superlattice with sharp interfaces whose period is randomly modulated is considered. The correlation function of the randomness of the superlattice is deduced for one-dimensional planar inhomogeneities. The dispersion law and damping of the spin waves are calculated at the boundaries of the Brillouin zones of the superlattice in the weak-coupling approximation.
