摘要
本文采用界面重标度方法,严格地求解了两个有限铁磁住自旋链层间为铁磁耦合的界面自旋波的本征值问题.获得了严格的和完全解析的界面自旋波的充要条件.
n this paper,the exact solutions of interface spin waves in a coupled system of two finite fer-romagnetic spin chains are investigated by use of the interface rescaling approach. The necessarytnd sufficient condition for the existence of such interface spin waves is obtained exactly and ana-lytically.
