摘要：
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.
