两层对称铁磁薄膜中的自旋波共振

Spin-wave Resonance in a Symmetrical Ferromagnetic Bilayer Films

采用量子力学方法研究了两层对称铁磁性薄膜的自旋波共振激发,计算了自旋波共振激发谱,特别讨论了表面各向异性对共振的影响.研究结果表明:在没有自旋波间相互作用的情况下,表面钉扎直接影响着自旋波的共振激发.

A symmetrical ferromagnetic bilayer film in an anisotropic magnetic field parallel to the surfaces is investigated by using the quantum method,and the spinwave resonant spectra are calculated.Especially,the effects of anisotropy to resonant excitation is discussed.
