| 摘 要： | 对双层铁磁薄膜构成的系统，考虑界面铁磁性和反铁磁性耦合x寸自旋波色散关系、波形演化及共振的影响．结果表明：层间耦合对自旋波的共振影响较大，即层间铁磁性耦合比反铁磁性耦合更易发生共振．

| Abstract: | Considering the interface couplings (ferromagnetic coupling and antiferromagnetic coupling),the spin-wave dispersion relations,wave forms and resonant spectra in ferromagnetic bilayers are studied.It is shown that interface compling has a large effect on resonant spectra,furthermore,the situation with ferromagnetic coupling is easier to resonate than that with antiferromagnetic coupling under the same condition. |

| Keywords: | interface coupling ferromagnetic bilayer spin-wave resonant spectrum |
