研究了磁性双层膜中的自旋波激发，特别着重地讨论了横向（平行于界面方向）的自旋波对于纵向（垂直于界面方向）自旋波的影响，给出了体系的能带结构和色散关系
The spin wave excitation in a magnetic bilayer is studied, and the influence of the transverse (parallel to the interface) spin wave on the longitudinal (perpendicular to the interface) spin wave is discussed. The energy band of the system Structure and dispersion relationship
