【Abstract】 The exact solutions of the low energy quantum eigenstates and eigenvalues of spin woves in a ferromagnetic bilayer system with periodical boundary conditions are studied by the interface rescaling approach and quantum theory. The relations between spin waves and interface coupling are discussed. It is shown that resonant confined models of spin wares occurs when the interface coupling is moderately strong.更多还原
