本文研究了磁场中层间为铁磁性和反铁磁性耦合的两个半无限铁磁自旋链中的界面自旋波及其存在条件．结果表明：在给定链的参数后，对于铁磁性耦合，最多可存在光学－光学型和光学－声学型两种界面自旋波，而对于反铁磁性耦合，则最多可存在光学－声学型和声学－声学型两种
In this paper, the interface spin waves and their existence conditions in two semi-infinite ferromagnetic spin chains with ferromagnetic and anti-ferromagnetic coupling between magnetic layers are studied. The results show that there are at most two kinds of interface spin-waves in optical-optical and optical-acoustic modes for ferromagnetic coupling given the parameters of the chain, and up to the optical-acoustic And acoustic - acoustic two
