摘要
Fe/Cu compositionally modulated films made by rf sputtering were investigated with ferromagnetic resonance.Spin wave resonances related to interlayer exchange coupling were observed and the phase change of the spin wave was shared by both the Fe and Cu sublayers.The effective spin wave dispersion coefficient was found to increase with increasing thickness of Cu sublayers.
