摘要： 计算了铁磁膜表面附近的层间交换积分,并推广至半三维铁磁体的情形.计算结果表明表面附近的原子之间交换作用大于体内原子之间的交换作用,这从理论上证实了Mills所作的假设.

关键词: 层间交换积分, 铁磁薄膜, 表面

Abstract: THe in Inwhayer exchange Paramters near the surface of a ferromagnetic film have been calcuated;and they have been extended to the case of the semi-infinite sample.The results exhibit that the exchange interaction near the surfare is greater than that of the bulk.This confirms theoretically the assumption made by Mills.

Key words: surface, interlayer exchange integral, thin ferromagnetic film
