| 摘 要： | 考虑表面各向异性场,在非周期性边界条件下应用界面重参数化方法精确求解了两层铁磁耦合薄膜中的低能自旋波本征值,同时给出对应的本征模.结果表明:在A～B两层铁磁膜中自旋波本征模存在3种形式,分别为体模、界面模和禁闭模;而且表面各向异性场对本征模的表面、界面和传播性质影响很大.

| Abstract: | An A - B ferromagnetic bilayer film is investigated under the nonperiodic boundery condition and anisotropic field at two surfaces is considered by using the rescaling interface approach. The quantum eigenproblems are researched for the low energy cases. The results show that there are three types of eigenmodes, i.e. body mode, interface mode and perfect-confined modes in the A - B ferromagnetic bilayer film. Moreover the anisotropic field at two surfaces greatly affects the surface, interface and propagation property of spin waves. |
