| Abstract: | The effect of bulk single uniaxial anisotropy on dispersion relations and resonant spectra of spin waves in bilayer films with antiferromagnetic coupling are investigated.It has been found that,with the uniaxial anisotropy constant increasing, all kinds of modes transform each other. While for the spectra, the resonant spectra of high energy confined modes are weakened, the resonance spectra of low energy confined modes and interfaces modes are strengthened. |
