摘要
本文研究了各向异性铁磁双层薄膜中的界面自旋波的本征值问题，获得了界面自旋波存在的充要条件．数值计算结果表明，临界值ＪＣＡＢ随各向异性参数的比值增大而单调增加。
In this paper,the exact solutions of interface spin waves in a bilayer system of anisotropy ferromagnetic films are investigated by the interface rescaling approach.The necessary and sufficient condition for the existence of such interface spin waves is obtained exactly and analytically.The change of condition for the existence of interface spin waves changing with anisotropy parameter is duscussed.
