摘要 在均匀强磁场下,研究了反铁磁层间耦合的自旋双链系统中的界面自旋波的存在条件,结果发现:不管耦合多弱都会存在声学-声学型界面自旋波;若存在能隙,还会存在声学-光学型界面自旋波. The existence conditions of interface spin waves of coupled two finite- ferromagnetic chains are investigated for anti-ferromagnetic coupling.It is shown that there must exist acoustic-acoustic interface spin waves for anti-ferromagnetic interface coupling.In addition,there may exist acoustic-optical spin waves if an energy gap exists.
