摘要
本文采用界面重标度方法严格求解了双层铁磁性薄膜中自旋波的本征值问题,结果表明:在一般情况下,自旋波分为扩展模,共振禁闭模,完全禁闭模和界面模四种类型。对各种模在体内和界面处的性质与特点,以及各层薄膜中自旋波的色散关系和能量范围作了详细讨论。
he exact spin-wave modes of a ferromagnetic doublelayer are investigated by the interface-rescaling approach. It is shown that all the modes can be classified into four kinds of modes: theextended, the resonant confined, the perfect confined and interface modes. The dispersion curvesof the modes i11 sublayers are given. The parities, the energy scopes and the bulk and interfaceproperties of these modes are discussed in detail.
