| 摘 要： | 以海森伯模型为基础,只考虑最近邻相互作用,在计入外磁场和非周期性边界条件下,应用界面重参数化(IR)方法,讨论了体各向异性场对界面自旋波存在条件的影响,结果发现:不管耦合多弱都会存在声学-声学型界面自旋波;若存在能隙,随着各向异性场的变化还会存在声学-光学型界面自旋波和光学-声学型界面自旋波。

| Abstract: | In this article,based on one-dimension Heisenberg model,the unsymmetric bilayer ferromagnetic and antiferromagnetic thin films are investigated by using the interface rescaling approach under nonperiodic boundary condition. Particularly,the effect of uniaxial anisotropy on the conditions for the existence of interface spin waves in a biferromagnetic or biantiferromagnetic interface are discussed. From above discussing,we can come to the following results:there are acoustical-optical spin waves no matter how... |
