An effect of dynamic pinning of spins at an interlayer boundary on the propagation of spin waves has been distinguished in two-layer epitaxial films of yttrium iron garnet. In ferrite films magnetized tangentially in fields #0<i 47гМ012, an interlayer exchange interaction gives rise to a pinning of spins at the boundary between layers. The effect of this interaction on the propagation of spin waves is minimal at degeneracy frequencies of the spin-wave-resonance spectra of the layers. © 1995
