【Abstract】 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.更多还原
