The spin‐wave spectrum of infinite ferromagnetic superlattices composed of two b. c. c. materials with exchange coupling between nearest and next‐nearest neighbours is analysed theoretically in the exchange‐dominated region. The appropriate dispersion equations are derived by the transfer matrix method. Some numerical examples are presented for superlattices with (100) interfaces.
