A possibility to observe huge lateral shift (Goos-Hänchen effect) of exchange spin wave reflected from the interface of two ferromagnetic materials is theoretically investigated. The strong dependence of this effect on the exchange coupling between two magnetic media as well as on the magnetic field is obtained. We show that nonzero interlayer exchange is necessary to observe the lateral shift of reflected spin-wave, and this shift can reach values up to a few hundreds of wavelengths. The observed effect can be a useful tool in investigation of the magnetic coupling between two magnetic materials also through nonmagnetic spacer.
