The influence of exchange coupling of layers on the propagation of mag
netostatic dipole volume waves in normally and tangentially magnetized
two-layer epitaxial ferrite structures is investigated. It is shown t
hat the indicated influence is manifested in the form of dynamic spin
pinning effects on the interlayer boundary and formation of a common d
ipole-exchange wave spectrum for the entire structure. In this case, a
t the synchronism frequencies of the dipole and exchange waves the los
ses of the dipole waves grow and anomalous segments appear in the disp
ersion. In films magnetized in the ''hard'' direction relative to the
axis of normal uniaxial surface anisotropy the magnetostatic dipole vo
lume waves can interact resonantly with the surface spin waves support
ed by the boundaries with pinned spins. (C) 1998 American Institute of
