摘要：

A microscopic theory is employed to investigate the spin-wave spectra of two-component ferromagnetic superlattices, where both materials may have nonuniaxial single-ion anisotropy. The calculations are carried out for the exchange-dominated regime and a transfer-matrix approach is used to simplify the algebra. Numerical examples are presented to illustrate our theoretical results, which generalize previous work in this field.
