摘要
研究了内部各向异性的Ａ－Ｂ结构的一维铁磁性超晶格自旋链，利用界面重参数化方法，给出了自旋波低能量子严格解．结果表明，超晶格自旋波分为非局域模，局域模和界面模三种类型．对各种模的性质与特点，以及自旋波的色散关系和能量范围做了讨论．
The exact solutions of spin wave modes of a one dimensional anisotropic ferromagnetic superlattices spin chain with A-B structure are investigated by use of the interface rescaling approach.The results show that the spin wave in the superlattice can be classified into three kinds of modes:the unconfined,confined and interface modes.The dispersion relations and energy scopes of the modes in sublayers are given.The bulk and interface properties of these modes are discussed in detail.
